File protection has improved and now keeps millions of daily transfers secure and compliant
In my organization, while using this tool, we found that there were a few files flagged as suspicious; however, those were not suspicious and it was a false positive, so that can be improved. False positive results were an issue, and it took time to scan files if the file size was greater than 1 GB. For larger files greater than 1 GB, it needs to be improved. In some cases, the reconstruction of the file led to a failure of code deployment and it flagged a valid file as malicious, which was not effective; however, in other types of files, it was very effective and could scan files properly. We have already covered all the main suggestions; however, it can be improved to reduce false positive results, and scanning could be faster to process more files in a day.

Real-time file security has reduced incident tickets and improves threat detection accuracy
The best features of Symantec Protection Engine include machine learning, file reputation, and real-time scanning. It efficiently handles heavy loads through ICAP and cloud-based processing, reducing the burden on endpoints compared to Trend Micro and other endpoint security solutions. Its centralized control is also noteworthy. Through machine learning, it detects both known and unknown malware and malicious URLs, in addition to performing signature-based scans that assist SOC teams in analysis. The solution is highly effective in leveraging both machine learning and file reputation. Regarding centralized control, it offers a unified management console for policy deployment and provides real-time visibility through dashboards, helping save significant administrative time. Symantec Protection Engine has had a positive impact on our organization by enhancing our overall security posture. It effectively blocks a high volume of file-based threats across more than 200 servers, saves SOC analysts time in endpoint remediation, and streamlines compliance processes. It further strengthens security through real-time scanning and machine learning-based quarantine, blocking phishing payloads in SharePoint uploads before they reach endpoints, thereby reducing incidents by 30–40% compared to signature-only tools.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"I like the simplicity, the way it works out of the box. It's pretty easy to run and configure. The integration of the network devices with the ICAP server was easily done."
"The effectiveness of the solution in blocking or sanitizing any content based on our policies is excellent."
"The best feature of MetaDefender is that it can isolate USB devices from the connected network, blocks malware and unsafe files, and ensures all endpoints follow security policy, so that my organization remains safe and reduces the risk of these threats."
"MetaDefender has impacted my organization positively by adding an extra layer of security to our file and content handling process, and through its CDR, it ensures that files are sanitized before they reach our environment, which has improved our security posture."
"MetaDefender has positively impacted my organization by reducing the risk of file-based attacks, which has significantly improved our overall defense against phishing and malware delivery techniques."
"The best features of MetaDefender include its ability to detect malware and vulnerabilities, which I also use at server levels, including production and testing servers, helping me identify and address vulnerabilities by applying patch updates."
"MetaDefender is leading with respect to competitors as an all-in-one platform because no other tool has all the platform built-in."
"MetaDefender is a useful tool for scanning all incoming and outgoing files and keeping our applications and servers in compliance, and I found it useful because we can integrate it with multiple file transfer tools such as Globalscape EFT, GoAnywhere, or Sterling, which is the best feature as it integrates with multiple tools."
"Symantec Protection Engine provides me with the option of both cloud and on-premise solutions, which stands out for both me and my clients."
"Symantec Protection Engine's been a game-changer for us at Kantar—blocks like 80-85% of file-based threats right at the gateway before they hit our 200 servers, cutting down endpoint incidents big time."
"The operational efficiency with the high-performance scanning of Symantec Protection Engine is very good."
"The best features that I like the most include the threat intelligence network, which is effective in protecting against evolving threats."
"The biggest advantage of Symantec Protection Engine is that one tool protects all, and it is centrally managed."
"Symantec Protection Engine has improved my security posture by helping me identify potentially malicious files before they reach users or critical systems, and the automated scanning process has also reduced manual efforts for my team, allowing us to focus on other security tasks and respond to threats more efficiently."
"What I appreciate in Symantec Protection Engine is the Virtual Policy Manager (VPM) and the Application Name feature, which are really effective."
"Symantec Protection Engine is a cheaper and rock-solid product where basic anti-spam features and threat intelligence are needed."
 

Cons

"The UI can be more user-friendly, and initial steps and policy tuning take some time."
"Some capabilities are lacking in reporting because we do not have full statistics that are easy for users to understand."
"From the last year that we integrated OPSWAT in our company, I have not seen any improvements."
"In some cases, the reconstruction of the file led to a failure of code deployment and it flagged a valid file as malicious, which was not effective; however, in other types of files, it was very effective and could scan files properly."
"In some cases, the reconstruction of the file led to a failure of code deployment and it flagged a valid file as malicious, which was not effective."
"The documentation is not well written, and I often need to talk with support."
"I would rate it an eight because its interface can be improved and it can improve their integrations as well, so there is room for improvement."
"One area where MetaDefender could improve is by making the user experience more intuitive, especially for new users, with clear guidance, simpler navigation, and a more detailed explanation of scan results and outcomes, which would enhance the effectiveness for users, while better onboarding and learning resources would help users get familiar with the different features more quickly."
"To improve Symantec Protection Engine, I suggest simplifying its integration with other tools, as it is more complex compared to Trend Micro and CrowdStrike."
"As for pricing, I would say it is a little expensive compared to competitors, and I think the vendor could achieve more market growth if the pricing were more reasonable."
"For the improvement of Symantec Protection Engine, the engine did not work with their basic engine when I was working, which was almost three or four years before."
"We have scenarios in which Symantec Protection Engine misses some threats, spam, and targeted attacks that Proofpoint can catch with AI security features."
"Price is a significant area for improvement. The pricing is quite expensive, and it is particularly high for regular customers."
"I would like to see improvements in reporting and troubleshooting capabilities for Symantec Protection Engine, as more detailed insights and simplified diagnostics would make day-to-day administration easier."
"I have concerns about scalability."
"While I have mentioned many advantages of Symantec Protection Engine, there are areas for improvement, particularly the dashboard features."
 

Pricing and Cost Advice

"We bought a three-year license, and that was pretty expensive. We agreed that it was really worth buying. It could be cheaper, but we understand that quality comes at a price."
