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.

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.

In life, various applications such as Internet social networking, audio and video, e-commerce, scientific experiments, and so on are constantly producing tens of millions, hundreds of millions, or even tens of billions of small files. The understanding of massive small files is usually defined by quantification. Files with a size of less than 1MB are called small files, and those with a number of millions or more are called lots of small files . Difficulties in small file transfer The transfer of massive small files is quite different from that of large files. The performance consumption and bottleneck of transferring large files are attributed to bandwidth, while the transfer of massive small files is different. Because the filehandle needs to be opened/closed frequently in the transfer of massive small files, but there is very little content to read and write after the files are opened, the bottleneck of the transfer of massive small files lies in IO performance. Mass small file transfer is a recognized problem in scientific and technological circles, and many technicians have been working hard for it. The following are two solutions given by Raysync, the leading brand of enterprise-level large file transfer. Breakthrough point of massive small file transfer solution 1. I/O read-write optimization technology I/O Input/Output, Raysync utilizes excellent I/O read-write optimization technology , supports up to 5000 read-write capacity per second, provides efficient support for massive small files, and provides high-speed transfer support services for massive files. 2. High-speed Transfer Protocol Raysync has independently developed high-speed transfer protocol, which breaks through the transfer defects of traditional FTP and HTTP and can effectively improve the existing transfer efficiency, reaching more than 100 times the traditional data transfer efficiency, ensuring the high-frequency and extremely fast transfer of massive small file data.

In the Internet age, data transfer and file synchronization are the basic tasks of daily business development of enterprises. And with more and more branches of enterprises, the amount of data is getting larger and larger, and problems such as the loss and leakage of enterprise core data in the process of file transfer and synchronization begin to stand out. How to make the files of each branch transfer quickly and synchronize the files between multiple servers and multiple data centers is a problem that enterprises need to pay attention to. At present, there are many software tools for file transfer and synchronization on the market, but there may be some problems: 1. Unsecure Some software may be constrained by the network environment, the distance of transmission or synchronization, etc. Files are easy to be lost and damaged during transfer or synchronization, and data loss will cause a serious blow to enterprises. 2. Troublesome Many software or tools have a single function and only support one-to-one file data synchronization or transfer application mode. Or the deployment process is complicated, and manual troubleshooting is needed after errors, which wastes time and labor cost. 3. Unreliable When millions of small files are synchronized or transmitted, packet loss may occur, resulting in incomplete and inaccurate transmitted or synchronized files. Raysync is definitely the best assistance of file transfer and file sychronization. First of all, Raysync can guarantee data security, and the bank standard AES-256 encryption ensures the data transfer compliance and security. Secondly, the Raysync self-developed transfer protocol can increase the transfer speed by 100 times in one second. Moreover, the enhanced file synchronization function of Raysync has established a data synchronization solution that meets the business scenarios of enterprise users through the core technologies independently developed such as high-speed engine technology and high-speed transfer protocol technology. Finally, regardless of distance and network conditions, the mechanism of Raysync file breakpoint resume and error automatic retransfer ensures automatic retransfer even if the transfer is interrupted due to unpredictable circumstances in the process of transfer, thus ensuring the integrity and accuracy of transfer results.
