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

"For one of my clients, a major bank in Turkey, they reported saving approximately 30 percent of their SOC time on analyzing emails since implementing MetaDefender."
"MetaDefender is 100% stable, making it one of the best cybersecurity solutions we offer, which provides confidence in promoting and recommending it to others."
"MetaDefender is flexible because, for a free product, you can enroll up to 50 devices, and I have only used about eight devices so far."
"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."
"The effectiveness of the solution in blocking or sanitizing any content based on our policies is excellent."
"The percentage of accuracy is great and the integration of multi-scanning and Content Disarm and Reconstruction affects my data security operations effectively because OPSWAT blocks the file types that we are not willing to have inside the company or are not approved."
"OPSWAT is the best alternative."
"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."
"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 provides me with the option of both cloud and on-premise solutions, which stands out for both me and my clients."
"What I appreciate in Symantec Protection Engine is the Virtual Policy Manager (VPM) and the Application Name feature, which are really effective."
"The best features that I like the most include the threat intelligence network, which is effective in protecting against evolving threats."
 

Cons

"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."
"Some capabilities are lacking in reporting because we do not have full statistics that are easy for users to understand."
"I did not manage to enroll my IoT devices, including my child's device running on iOS and some Amazon products."
"The main improvement needed is pricing because, as an enterprise solution, smaller partners do not often receive the attention they deserve."
"The documentation is not well written, and I often need to talk with support."
"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."
"From the last year that we integrated OPSWAT in our company, I have not seen any improvements."
"Most of the time, in our experience at Danet Communications, we work with government offices, and they need the CDR. However, because CDR is affecting files such as MSI and EXE files, they are always creating new passes of scanning."
"I have concerns about scalability."
"While I have mentioned many advantages of Symantec Protection Engine, there are areas for improvement, particularly the dashboard features."
"Price is a significant area for improvement. The pricing is quite expensive, and it is particularly high for regular customers."
"To improve Symantec Protection Engine, I suggest simplifying its integration with other tools, as it is more complex compared to Trend Micro and CrowdStrike."
 

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."
