Ravi Raushan Singh - PeerSpot reviewer
Senior Infra Architect at a educational organization with 11-50 employees
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.
Abhimanyu Das - PeerSpot reviewer
Senior Cybersecurity Engineer at Kyndryl
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

"Deep CDR is a strong feature of MetaDefender that we have configured using a sandbox license. While it is scanning the file, it breaks the file and checks each component of that file. By using the sandbox feature, it will isolate the particular file temporarily and check whether anything suspicious is detected. If there is a malicious threat, it will remove that and reconstruct the file, providing the copy to the user. That is a very strong feature provided by MetaDefender."
"Combining multiscanning with CDR strengthens my data security operations by providing deeper detection and safer file outputs before files enter the environment."
"MetaDefender is leading with respect to competitors as an all-in-one platform because no other tool has all the platform built-in."
"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."
"I assess the effectiveness of Deep CDR in reconstructing files safely and without signatures as a ten out of ten, as I really appreciate how it is done."
"The best feature MetaDefender offers is Content Disarm and Reconstruction because if there is malware in a particular file and the agent is sitting on it with Content Disarm and Reconstruction enabled, it is going to remove the malware and give you the exact file you need without you even being aware, which is a very good technology."
"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 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."
"The operational efficiency with the high-performance scanning of Symantec Protection Engine is very good."
"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."
"The biggest advantage of Symantec Protection Engine is that one tool protects all, and it is centrally managed."
"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'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."
"Symantec Protection Engine is a cheaper and rock-solid product where basic anti-spam features and threat intelligence are needed."
"The best features that I like the most include the threat intelligence network, which is effective in protecting against evolving threats."
"Symantec Protection Engine provides me with the option of both cloud and on-premise solutions, which stands out for both me and my clients."
 

Cons

"The main improvement needed is pricing because, as an enterprise solution, smaller partners do not often receive the attention they deserve."
"We could enhance the user interface and user experience, as the platform has many security capabilities, but some configuration and policy management tasks can take time to understand, especially for someone using the product for the first time."
"Reporting still requires improvement, but otherwise the solution is excellent."
"MetaDefender is strong, but integration with SIEM and SOAR platforms could be smoother, and faster scanning for large files would be welcome."
"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."
"I would like to see improvements in the tool's automation capabilities."
"In my opinion, MetaDefender could improve its async version of their APIs, as the documentation is not that good for the async APIs and can be a bit complex to navigate for integrations."
"What I would like to see improved in MetaDefender includes reducing the high cost of the license, as the pricing is very high."
"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."
"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."
"We have scenarios in which Symantec Protection Engine misses some threats, spam, and targeted attacks that Proofpoint can catch with AI security features."
"To improve Symantec Protection Engine, I suggest simplifying its integration with other tools, as it is more complex compared to Trend Micro and CrowdStrike."
"I have concerns about scalability."
"Price is a significant area for improvement. The pricing is quite expensive, and it is particularly high for regular customers."
"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."
"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."
