Ravi Raushan Singh

Senior Associate 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.

IT Security Manager at a insurance company with 1,001-5,000 employees

Has improved our vulnerability tracking and supports cloud-based monitoring with scheduled scans

We don't have any issues with Tenable One Exposure Management Platform. It works well for us, but the only problem is the licensing aspect. In the license, it becomes problematic because when we go to cloud security for vulnerability management, it will take five licenses instead of the one-on-one license that vulnerability exposure management requires. The license needs to be reviewed.

Quotes from Members

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

Pros

"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."

"OPSWAT is the best alternative."

"The effectiveness of the solution in blocking or sanitizing any content based on our policies is excellent."

"I assess the effectiveness of MetaDefender in blocking or sanitizing content based on policy as very good."

"My advice to others looking into using MetaDefender is that if you are looking ahead at a solution which can be implemented quickly and at a lesser cost, go ahead with it."

"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."

"MetaDefender prevents malicious or weaponized files from reaching users while reducing the risk associated with unknown, zero-day file-based threats."

"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."

More MetaDefender pros

"The solution is very easy to set up."

"Tenable EP is a great overall product for our customers; it's great at helping customers to identify current risks, it helps customers manage their risk, users can effectively analyze risk and can assign team members to take a look at items as well, the solution is very easy to set up, technical support is very helpful and responsive, and the pricing is pretty good."

"The feature of vulnerability management and discovery is what I use."

"The product gives us a lot of insight."

"For me, the setup has been an easy process."

"We find Tenable One Exposure Management Platform vulnerability prioritization effective overall because, with the scheduled scan running on our set schedule, we can remediate any findings and check on the next schedule if issues are closed, making it much easier for us to monitor vulnerabilities."

"I think it's a good product for risk-based or exposure-based vulnerability management."

Cons

"From the last year that we integrated OPSWAT in our company, I have not seen any improvements."

"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."

"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."

"The UI can be more user-friendly, and initial steps and policy tuning take some time."

"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."

"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."

"What I would like to see improved in MetaDefender includes reducing the high cost of the license, as the pricing is very high."

More MetaDefender cons

"The license needs to be reviewed."

"It would be nice if the product provided an agent for enforcing policies."

"The sensor update is a challenge that Tenable needs to address. Sometimes they behave abruptly, requiring me to rework reinstalling the sensors on the endpoints."

"Tenable needs to provide a better way to manage private clouds."

"The product has limited reporting capabilities and it isn't great at allowing for customization in reports."

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."

"The pricing is fair."
