"Consistent Background Scanning with Easy to Understand Results"
What do you like best about MetaDefender?

File scanning runs consistently in the background and we have not seen noticeable slowdowns in applications or file services. The scan results are easy for non security teams to understand, which helps reduce escalations to IT. Integration was also straightforward, allowing us to add file inspection into existing systems without introducing new tools for staff to manage. Review collected by and hosted on G2.com.

What do you dislike about MetaDefender?

The main effort is during rollout. Policies need careful adjustment so business files are not blocked unnecessarily. Once tuned, ongoing maintenance is minimal. Review collected by and hosted on G2.com.

"Seamless Integration and Robust Protection for Real World Pipelines"
What do you like best about MetaDefender?

MetaDefender fits well into real application pipelines and does not require heavy redesign. File scanning is fast and reliable, even under load, and the API is easy to automate. The combination of multi-engine detection and file sanitization gives strong protection without forcing users to change how they work. Logs and results are clear enough to connect with SIEM and monitoring tools. Review collected by and hosted on G2.com.

What do you dislike about MetaDefender?

Policy tuning takes some effort at the start, especially for archives and uncommon file types. Careful testing is needed to avoid blocking safe files. Review collected by and hosted on G2.com.

Policy tuning requires attention, especially when dealing with archives or mixed file types. Early testing is important to prevent overly strict rules from interrupting normal traffic. Review collected by and hosted on G2.com.
