When employees leave their jobs, they take away the important data of the company or even destroy or disclose the data of the enterprise. The losses caused are fatal to the enterprise. Where are the materials produced by our employees stored? Is there any trace for employees to share or download information? Imagine that the company spent a lot of time and energy and finally accumulated a lot of customer materials, core technical documents, product publicity materials, etc., but because of the departure of employees, these valuable materials were destroyed or damaged. The materials accumulated by enterprises in the process of production and operation are very important. In the Internet age, data guides everything. By analyzing the data, enterprises can effectively grasp market changes, adjust business strategies in time, broaden development channels, and increase profits, and increase profits. The collation and analysis of big data can provide effective help for the development of enterprises: - Make enterprise products more in line with consumer demand Through big data analysis and design of consumer demand products, the products are more in line with market demand and more in line with the needs of users. - Help enterprises to target customers Through the big data analysis, to analyze and mine customer resources, customer distribution, etc., and help to form enterprise-based resource distribution map. - Help enterprises provide better promotion programs and enhance transformation Through data analysis, the operation direction of the enterprise becomes more intuitive, so as to choose a more suitable promotion direction and marketing platform and improve the operation effect of the enterprise. Enterprise data is so important that tools are needed to ensure data security and improve data distribution efficiency. File transfer software can manage data and ensure safe and efficient data transfer. File transfer software is probably the best tool for enterprises to protect and use data. Using file transfer software, enterprises can send large files and massive files effortlessly, with little or no downtime, which is a great improvement on traditional file transfer solutions . Some MFT solutions, such as Raysync, allow users to send files or folders of any size, thus eliminating the trouble of using complex and time-consuming FTP solutions or email servers that cannot handle large files. Static data or data in transfer appear in encrypted form. Raysync can also generate detailed report logs of any operations such as uploading, downloading, and sharing by users, so that the data can be checked, controllable, and traceable. In addition, the Raysybc has an authorization policy, and the administrator can set the authority of the sub-account by himself so that the right person can use the right authority. Raysync Large File Transfer solution can provide functions such as data center and network security, including firewall and intrusion prevention equipment. There are many other security functions available, and the functions are increasing continuously, ensuring that the requirements of government and industry for file security are met.

E-mail is still the most popular attack medium. Legitimate e-mails are attacked during transmission and hijacked in complicated ways, while phishing emails try to deceive people with fake addresses, which is a typical phishing attack . How to respond to the chain attach via email? Virus software purchases an email account through the email response chain. Attackers use phishing, violence or social engineering to access one or more email accounts, and then start to observe the conversation, and seek opportunities to send malicious software or malicious links to one or more participants in the ongoing communication chain. What types of malware use response chains as attack vectors? In 2017, the attack on the email response chain was first discovered. In 2018, Gozi ISFB/Ursnif Banking Trojan horse activities also began to use this technology; In other cases, attackers break legal accounts and use them to take over existing threads and spam attacks on other recipients. Malicious attachments can use VBScript and PowerShell to transfer workloads, such as emote, Ursnif, and other loaders or bank trojan malware. Ordinary fraudulent emails are usually sent in the form of topics or short messages, which are easy to identify and have less chance of being deceived. However, attacks through e-mail response chains are often carefully considered, without grammatical errors and with clear semantics. This means that even the most cautious and well-trained employees may become victims. Four methods to prevent email response chain attack Since the response chain attack is based on account compromise, it should be ensured that all employees of the company follow the verified security procedures. These include two-factor or multi-factor authentication, with a password set for each account. Secondly, the use of Office macros should be restricted or completely prohibited as much as possible. Although these are not the only means by which malicious attachments may endanger devices, macros are still common attack vectors. Introducing safety awareness training is of great help to train employees to understand the dangers of phishing. E-mail users need to raise people's awareness of phishing attacks and how attackers develop their technologies. Information assets are very valuable for enterprises, so it is better to deploy a data transfer solution as soon as possible instead of preventing this and that. Raysync adopts self-developed transfer protocol, which can help enterprises to quickly distribute large files or massive small files, and can provide the highest transfer speed with minimum system overhead regardless of the distance of transfer or the strength of network conditions; Security is also the focus of Raysync. The whole process of file transfer adopts financial AES-256 encryption transfer to ensure data security. The mechanism of breakpoint continuous transfer and error automatic retransfer ensures that the transfer can continue from the breakpoint after unexpected interruption of transfer, ensuring the integrity and reliability of file transfer, and monitoring the whole process log to ensure considerable, searchable and traceable data.

For decades, there has been no good solution for enterprises to balance security and productivity in file sharing. Especially in this fast-paced era, people are not satisfied with traditional disk movement, FTP, and email to complete file sharing. People want to work collaboratively anytime and anywhere, so more and more people are turning to file sharing solutions. However, it is worrying that according to the research report, 50% of enterprises have no policy on file-sharing tools. Even if there is a policy, 48% said they would not implement it. More importantly, 69% of small and medium-sized enterprises don't even know whether their employees are using unapproved file-sharing tools or dangerous file-sharing tools. How to strike a balance between employee productivity and protecting critical data? Many employees of enterprises are already using file-sharing software. As mentioned above, this may expose the data of enterprises to the risk of data leakage because of IT compliance. Perhaps it is not intentional for people to leave the company with sensitive documents when they move , but the risks always exist. Instead of letting employees look for various file-sharing tools spontaneously, it is better to integrate a compliant and controllable file sharing tool into the existing office software of enterprises to create a safe and comfortable office environment. This file sharing tool needs to meet the following characteristics: - Improves the employee productivity - Easy to use - Security, data sharing process security and storage security - Compliance-meet the strict compliance requirements of the industry - Good integration Raysync - the fastest and most secure file sharing tool - Raysync has a self-developed high-speed transfer protocol, and the bandwidth utilization rate is over 96%. It meets the needs of enterprise large file transfer and massive small file-sharing in multiple dimensions, effectively helping to improve productivity; - It takes three easy steps to complete the client deployment and you don't need to take time to configure it. - In terms of security, TLS+AES-256 encryption technology and multiple firewalls have reached the international top financial level security. - Support mainstream servers and desktop operating systems, support various storage devices and cloud service models and maintain high integration with existing business systems of enterprises.

Nowadays, the software development of technology and electronics companies requires frequent exchange and cooperation between on-site teams and off-site teams on source code. Due to the influence of the nature of work, there are usually urgent deadlines. Therefore, many teams will choose some tools to help them finish their work quickly and safely. E-mail: is a kind of transfer way people would like to choose, which is very convenient and easy-to-use. However, the size of attachments sent by free email is no more than 30M, and the size of attachments sent by paid email is almost 100M, which can not meet the needs of the data exchange of large projects. Affected by network conditions, transfer distance, etc., the quality of transfer data is compressed, or more seriously, transfer data errors and losses occur. Transfer through the mailbox, without any audit and log records, thus controllable visibility is extremely poor. FTP : Most technology companies build, repair and troubleshoot software through FTP. Because these solutions have almost no rights management and almost no audit and tracking control, IT departments have the least visibility and control over intellectual property rights. Free File Sharing Solutions: Nearly 57% of engineering teams use free file sharing solution, but this solution has security and intellectual property risks. Free applications like Google Cloud are popular among developers because of their ease of use, but they are not designed to protect sensitive company data through functions such as encryption and anti-virus scanning. These tools will also enhance the dispersion of corporate data. Enterprise-level File Transfer Solutions: These enterprise-level file transfer solutions provide a set of more powerful tools to protect and manage software versions, patches, and error logs. Among the 100 senior company managers and IT executives surveyed, 59% have improved their efficiency and security by using enterprise-level file transfer solutions, and centralized control of the exchanged files and contents. Raysync provides enterprises with one-stop efficient and safe file transfer solution. At present, 2W+ enterprises are using Raysync to improve the transfer efficiency and security of enterprises.

The Raysync under Yunyu Technology provides high-performance, stable, and safe data transfer services for IT, film and television, biological genes, manufacturing, and many other industries. At present, 2W+ enterprises adopt the big data transfer scheme provided by Raysync to solve the data interaction problems faced by enterprises. This time, a well-known film and television production company in Shanghai cooperated with the Raysync team. For the film and television production industry, post-editing is the process of re-creation, and its importance is equal to that of pre-shooting. TV series, movies, and so on all need to cut out story clues and plots from massive film and television materials, and also need to add animation, sound effects, flowers, and the other rendering atmosphere to strengthen emotions and enhance the visibility of works. In the post-production process, the flow of video materials runs through the whole business process. In addition to excellent non-editing software and non-editing workstations, enterprises also need to deploy a set of high-efficiency and high-stability transfer software to ensure the transfer quality of massive materials and ensure the successful completion of film production. Project Difficulties The company is headquartered in Shanghai and needs to exchange materials with the team in Japan. Due to the extensive use of CG visual effects, VR shooting, 3D technology, etc., the film and television material files are getting larger and larger, with dozens of GB and hundreds of TB at every turn, and the transfer frequency is high, which requires to transfer almost every day. In addition, the company also has certain requirements for the timeliness of material transfer. Before using Raysync, the company mainly used FTP and other traditional methods to transfer files, which often took two or three days to complete the transfer of a 10GB material, which seriously affected the production progress. 1. A film may be shot in many places, and the changeable shooting location means that the transfer distance of materials is also changeable, including remote transfer, transnational transfer, intercontinental transfer, uploading, downloading, sharing, and other operations. The transfer scene is complex, with a large number and large capacity of transmitted materials, and the material flow is extremely slow. Such a complex transfer scene leads to the extremely unsmooth business process of the film and television production company, and the production progress is seriously lagging behind. 2. As mentioned above, the shooting location is changeable, which also means that the network conditions of the shooting location are uncontrollable. If the materials are transmitted in remote areas with difficult conditions or deserts, the uploading and downloading of videos will sometimes be interrupted due to the poor network environment, and the team sometimes has to arrange special personnel to monitor the data transfer. Even so, there will often be material damage, video mosaic, etc., and the producer's efforts will be burned. Unsafe transfer methods may also lead to the loss and theft of materials during the process of transfer. The content of the film and television industry is paramount, and the confidentiality of the data is very high. The material in the transfer process is maliciously stolen, which may eventually cause the copyright of the film to be infringed. 3. Production teams are scattered all over the world, and the whole team needs close cooperation to ensure the efficient completion of tasks. When the production team is in different places and across countries, the transfer of massive film and television materials becomes a problem. With the popularization of high-definition 4K and 8K, the material capacity of the film and television industry is also increasing. Traditional network transfer methods such as FTP are difficult to ensure the efficiency of large file transfer, which seriously affects the production cycle. This method has been gradually abandoned by film and television organizations. For the needs and pain points of the film and television post-team, Raysync has launched a data transfer solution for the film and television industry. Raysync is based on UDP transfer protocol, which overcomes the bottleneck of traditional data transfer software , provides the highest transfer speed, perfect integration, and control functions for the film and television industry, and brings real high-performance data transfer experience for the film and television industry. The Solutions of Raysync Raysync has a deep insight into the pain points of the film and television industry, helping customers install and deploy the Raysync server in Shanghai. Japanese team members can log in to Raysync through IP address+port number, and easily upload and download film and television materials. Comparison of the transfer data before and after using Raysync: The company used FTP transfer before. After comparison, the transfer speed has been significantly improved after using Raysync, and the upload and download speed has exceeded 90% of FTP; Raysync shortens the transfer time of video materials to the greatest extent. It takes 192 minutes and 39 seconds to transfer 10GB files from Shanghai to Japan by FTP, while it takes only 12 minutes and 42 seconds to transfer by Raysync. Raysync saves the team at least 93% of the transfer time. The Raysync also brings the following conveniences to the film and television team: Complete team and authority control In the traditional FTP solution, the folder structure and permission control are relatively simple, and Raysync provides more detailed, scientific, and complete file and personnel management functions, which meets the multi-line and complex work requirements of the film and television industry. Supports automatic management of the transfer tasks Through Raysync Client, film and television workers can conveniently monitor the transfer of material, uploading and downloading tasks, obtain information such as transfer progress, speed, and status, and can pause, renew and cancel the transfer tasks. Supports the switching of Chinese and English The film and television teams are scattered all over the world, and the Raysync switching function between Chinese and English perfectly overcomes the language barrier of transnational transfer, and the global data transfer is unimpeded. The Features of Raysync Optimize the transfer performance, and transfer video materials efficiently When the network environment is very poor, the transfer is often interrupted due to network failures, sudden power outages, etc. The Raysync breakpoint resume function ensures that the remaining materials can be downloaded from the recording position after the system is started again, with a packet loss rate of 0.00%. Fast file transfer shortens the production cycle Through the optimization of Raysync protocol and automatic compression and packaging, the network bandwidth resources can be utilized and saved to the maximum extent, and the data transfer experience can be provided for enterprise users. The transfer speed of video backhaul can reach more than 100 times that of traditional means, which greatly shortens the time consumption of video material transfer. Enterprise-level security to avoid copyright infringement Raysync has many data encryption schemes, which form an encryption tunnel between the sending and receiving ends of data to ensure that the material files will not be stolen or leaked during the video return process, so as to avoid the infringement of film copyright. Flexible and efficient business management Raysync completely records the complete behavior logs of users such as login, logout, upload, download, and link sharing, and auditors can regularly audit the operation behaviors of members, so as to guard against the occurrence of malicious data leakage.

Many enterprises only need some instant messaging tools to handle the daily file exchange work, and they only need to accelerate the transfer of large data sets at certain specific times or situations. Some enterprises have only a handful of demands for the accelerated transfer of big data, and the traditional monthly or yearly plan will inevitably lead to unnecessary idleness and waste of resources. Raysync now supports pay-as-you-go service, and enterprises can start big data acceleration service by selecting corresponding traffic packets.

Case study: An intelligent technology company urgently needs to transfer 8TB of R&D data to the Swiss branch, and there is no urgent need for big data transfer at ordinary times. Customer demand analysis: 1. "Urgent" demand: R&D data needs to be distributed to the Swiss branch as soon as possible and put into production immediately. If you mail the hard disk or the traditional FTP transfer method, you can't meet the customer's demand for the timely delivery of the data. 2. Cost control requirements: The companies’ big data transfer has the characteristics of low frequency. The company has not set enough budget for the big data transfer project. After understanding the data transfer solutions in the market, it is found that a set of software needs to cost hundreds of thousands, which will cause serious waste of resources and financial resources, which is inconsistent with the needs of the company. 3. Flexible requirements: Just like the urgent transfer of 8TB files to Switzerland this time, we can't predict whether the next large file transfer task will also be affected by unexpected factors, that is, the transfer software pay-as-you-go plan is the best choice for enterprises. 4. Data security requirements: Production R&D data is the lifeblood of enterprise production and operation, and its importance is self-evident. In the process of transfer, due to poor network environment and long transfer distance, it may lead to low transfer efficiency, and file transfer security loopholes are more likely to occur. The leakage of R&D data will bring a devastating blow to enterprises. Considering the need to transmit enterprise R&D data overseas, the company has high requirements for the security of the transfer process. 5. Requirements for easy-to-use: The company's big data transfer frequency is low, the interface is simple, the operation is simple, and the convenient and fast transfer software is deployed, which will greatly reduce the time cost for employees to learn to use the software, and the work of data uploading and downloading will get started faster. The Raysync server is deployed at the Nanjing headquarters of the company, and the team members of the Swiss branch can log in to Raysync through IP address and port number, so as to easily upload and download the production R&D data.

In the Internet age, speed determines efficiency. In the process of enterprise production, it is necessary to exchange and carry information and data, and then file transfer is necessary. All aspects of the industry involve the transmission of large files. For example, the film and television industry needs to transmit video materials every day, and video data as small as tens of megabytes and as many as several tons should be transmitted from the shooting place to the video center. Or meteorological observation points around the meteorological industry need to make meteorological observations in real-time and summarize the data to the Meteorological Bureau immediately and effectively, so as to issue accurate weather forecasts. Faced with such a huge amount of data, how can enterprises transfer large files safely, stably and efficiently, then the large file transfer tool is essential for enterprises. Small file transfer can be carried out by using network sharing tools such as WeChat, email, etc. Although the point-to-point transfer is convenient to use, there is a limit to file size, and the speed is sometimes slow according to the network environment. But it is a convenient choice for individual users to transfer small files. Large file transfer using Filezilla, network disk, and so on is stable and supports breakpoint continuous transfer. However, the speed of large file transfer is extremely slow, the packet loss rate is high, the transfer reliability is poor, and the speed of transnational transfer is particularly low. It is inconvenient to use the network disk, and it is necessary to upload the file to the terminal before downloading it. In addition, for large files, it is also possible to send a large number of files to their destinations. However, unpredictable problems such as hard disk damage and express delivery delay easily occur during transportation, and the real-time performance cannot be achieved. Speed determines efficiency, time determines money. Nowadays, big data is very important for enterprises, and huge data must be transmitted quickly in order to grasp the information in the hands of enterprises in real-time. Realizing the fast transfer of large files can improve work efficiency, and make enterprises one step ahead of others. According to the needs of the film and television production industry, Raysync Transmission has launched a solution for the film and television production industry based on ultra-high-speed transfer protocol. Thoroughly overcome the inherent bottleneck of traditional data transfer methods, such as FTP and HTTP, and provide the maximum transfer speed that is not affected by network conditions and transfer distance for video transfer, video upload, video return, and other audio-visual content transfer, thus providing the real high-performance data transfer for the film and television production industry.
