Featured Reviews

Israel Cavazos Landini - PeerSpot reviewer
Weekly insights and risk analysis facilitate informed security decisions
I appreciate the weekly insights Zafran provides, which include critical topics for networks and IT security, allowing us to evaluate which insights apply to our environment. The organization score feature is valuable to keep the leadership team updated on how our infrastructure fares security-wise. The applicable risk level versus base risk level feature is beneficial because prior to Zafran, we only used the base risk level, but now understand that risk depends on the asset itself. Zafran is an excellent tool.

Affordable tool boosts code scanning efficiency but faces integration hurdles
I lead a code security practice for our organization. We integrated Snyk into our GitHub, using CLI to automatically scan codebases and identify issues. We are a large organization with three independent entities, consolidating Snyk across all entities.  We also provide access through numerous…
HarshBhardiya - PeerSpot reviewer
Provided increased visibility across the organization's servers
The user interface of Tenable Nessus feels outdated and could be more user-friendly. Additionally, the documentation is not well-organized, which can be confusing when searching for solutions or specific information related to Tenable Nessus Professional. The reporting feature could be improved by allowing users to create their own templates instead of relying on predefined ones.

Quotes from Members

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

Pros

"We are able to see the real risk of a vulnerability on our environment with our security tools."
"Zafran is an excellent tool."
"Overall, we have seen about eighty-seven percent reduction of the number of vulnerabilities that require urgency to remediate, specifically the number of criticals."
"Zafran has become an indispensable tool in our cybersecurity arsenal."
"We saw benefits from Zafran Security almost immediately after deploying it."
"It has a nice dashboard where I can see all the vulnerabilities and risks that they provided. I can also see the category of any risk, such as medium, high, and low. They provide the input priority-wise. The team can target the highest one first, and then they can go to medium and low ones."
"I am impressed with the product's security vulnerability detection. My peers in security are praising the tool for its accuracy to detect security vulnerabilities. The product is very easy to onboard. It doesn't require a lot of preparation or prerequisites. It's a bit of a plug-and-play as long as you're using a package manager or for example, you are using a GitHub repository. And that is an advantage for this tool because developers don't want to add more tools to what they're currently using."
"The solution's Open Source feature gives us notifications and suggestions regarding how to address vulnerabilities."
"We use Snyk to check vulnerabilities and rectify potential leaks in GitHub."
"Snyk is a good and scalable tool."
"The most valuable feature of Snyk is the SBOM."
"It has improved our vulnerability rating and reduced our vulnerabilities through the tool during the time that we've had it. It's definitely made us more aware, as we have removed scoping for existing vulnerabilities and platforms since we rolled it out up until now."
"Snyk categorizes the level of vulnerability into high, medium, and low, which helps organizations prioritize which issues to tackle first."
"It gives you an unlimited IP scan."
"Tenable Nessus is an absolutely stable and fantastic product."
"The features I personally like include host discovery."
"The most valuable feature of Tenable Nessus is vulnerability detection."
"The most valuable aspect of this solution is that you receive the entire report, which details the breakdown, especially in terms of critical, high, low, and mediums."
"The most valuable feature of Tenable Nessus is website scanning."
"The reports are pretty nice and easy to understand."
"I have found the vulnerability assessment and the reports to be useful."
 

Cons

"I think the ability to have some enhanced reporting capabilities is something they can improve on, as they have good reports but we have asked for some specific reporting enhancements."
"The dashboarding and reporting functionality of Zafran Security is an area that definitely could use some improvements."
"Initially, we were somewhat concerned about the scalability of Zafran due to our large asset count and the substantial amount of information we needed to process."
"I think Snyk should add more of a vulnerability protection feature in the tool since it is an area where it lacks."
"The reporting mechanism of Snyk could improve. The reporting mechanism is available only on the higher level of license. Adjusting the policy of the current setup of recording this report is something that can improve. For instance, if you have a certain license, you receive a rating, and the rating of this license remains the same for any use case. No matter if you are using it internally or using it externally, you cannot make the adjustment to your use case. It will always alert as a risky license. The areas of licenses in the reporting and adjustments can be improve"
"I use Snyk alongside Sonar, and Snyk tends to generate a lot of false positives. Improving the overall report quality and reducing false positives would be beneficial. I don't need additional features; just improving the existing ones would be enough."
"It would be great if they can include dynamic, interactive, and run-time scanning features. Checkmarx and Veracode provide dynamic, interactive, and run-time scanning, but Snyk doesn't do that. That's the reason there is more inclination towards Veracode, Checkmarx, or AppScan. These are a few tools available in the market that do all four types of scanning: static, dynamic, interactive, and run-time."
"One area where Snyk could improve is in providing developers with the line where the error occurs."
"The general input I have is that there is an opportunity for them to better align with other similar tools and better align with similar capabilities that cloud suppliers deliver natively."
"The solution could improve the reports. They have been working on improving the reports but more work could be done."
"Snyk's API and UI features could work better in terms of speed."
"They should try to create an all-in-one solution."
"The product must be more comprehensive."
"The most that Tenable Nessus could improve is its speed because they might have put a lot of effort into compatibility issues that downgrade the speed."
"The solution could improve security updates."
"Lacks some penetration testing-related services."
"The tool needs to upgrade asset tracking."
"Tenable Nessus could improve the reporting."
"The price could be reduced."

"The product's price is okay."
