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.

Automated insights streamline data security assessment

For Amazon Inspector, we have many EC2 or virtual machines deployed inside our AWS environment, and the problem is that the existing package deployed inside this EC2 instance has already outdated packages. As we progress with time, this package needs to be updated for security enhancement, which requires us to uninstall the package, install the new version, and then we should be fine. However, the challenge comes with how to scan all our EC2 instances for security vulnerabilities, which is currently managed by Amazon Inspector. Amazon Inspector can scan EC2 instances or ECR, which is the ECR registry where we can save artifacts Docker images. Amazon Inspector can also scan Docker images uploaded to ECR for Elastic Registry service, and it can scan databases and S3 based on the latest updates. I noticed this from a couple of months ago, and it provides huge benefits for security. Regarding the best features of Amazon Inspector, it gives us a list of all existing outdated packages as part of a deployed package on EC2 instances or specific Python packages that are part of the Docker file and the Docker image itself, which are causing security concerns. Amazon Inspector can list these security concerns and offer guidance on how we can remediate it by updating the package to a specific upper version or something similar.

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The user interface of Tenable Nessus feels outdated and could be more user-friendly.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

"Zafran has become an indispensable tool in our cybersecurity arsenal."

"Zafran is an excellent tool."

"We are able to see the real risk of a vulnerability on our environment with our security tools."

"We saw benefits from Zafran Security almost immediately after deploying it."

"Overall, we have seen about eighty-seven percent reduction of the number of vulnerabilities that require urgency to remediate, specifically the number of criticals."

"Amazon Inspector is highly stable, rated ten out of ten, and this stability impacts business security and administration positively."

"The integration of Amazon Inspector with other AWS services has enhanced our security. Security Hub is a major asset because it allows us to centralize data from various AWS services. We can integrate third-party tools as well. It is just a single-click option."

"The most valuable feature of Amazon Inspector is the categorization of findings, which filters vulnerabilities by instance, container image, container repository, and Lambda function."

"It operates continuously, so as soon as resources are created, it scans them for vulnerabilities."

"The scalability of the solution itself is unparalleled."

"I recommend Amazon Inspector because it allows the automation of processes and requires less manual monitoring."

"The vulnerability discovery is valuable, and they also rank those vulnerabilities for you. So, you could rapidly attack some of the higher, severe vulnerabilities as they pop up, if they do pop up."

"The findings dashboards are neat and easy to understand, offering clear demarcations for different types of findings and detailed insights into specific vulnerabilities and their associated instances. It is not a place where everything is dumped together. It offers an easy-to-understand layout."

More Amazon Inspector pros

"Nessus is effortless to integrate."

"The most valuable feature of Tenable Nessus is website scanning."

"The most valuable features are that it's fast, it's easy to use and it provides good reports."

"It's scalable."

"I like its ease of use. It has the script that is pre-built in it, and you just got to know which ones you're looking for."

"The scanning capabilities are most valuable when compared to Nessus."

"Ease of reviewing scores, identifying vulnerabilities, and getting information on them."

"It provides multiple recommendations towards the remedy of vulnerabilities."

More Tenable Nessus pros

Cons

"The dashboarding and reporting functionality of Zafran Security is an area that definitely could use some improvements."

"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."

"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."

"One major area for improvement is remediation. My team works on remediating findings over time, likely using available patches. However, easier integration with Amazon's patching services would be very helpful."

"One area for improvement in Amazon Inspector is the automation aspect."

"It has automated vulnerability assessment, yet I seek more flexibility in defining custom vulnerability checks tailored to my needs, which is more difficult."

"The most challenging aspect I faced with Amazon Inspector during integration was automating the remediation process."

"There is room for improvement in the scanning capabilities. I'd like to see broader coverage in terms of the vulnerabilities detected."

"It has a limited scope. So, AWS Inspector primarily focuses on the security of the EC2 instance. So, if your architecture includes other AWS services, then you may need to use additional tools for your comprehensive security assessment. So that is one con. Another is, like, we have a dependency on agents."

"There isn't too much to improve right now. Scanning on demand or as a part of the pipeline versus a post pipeline solution would be good, but it is not a deal breaker by any means."

"The other point is that the reporting features of Inspector need improvement. For example, I am in an organization with millions of CVEs, and getting an overview of all this is challenging."

More Amazon Inspector cons

"The solution could improve by having better integration with different vendors' IPS solutions. The ACLs and IPS policies signatures should be enabled based on the results of Tenable Nessus automatically, we currently have to do it manually which is very time-consuming. It has done a good job integrating with Fortinet but we would like it to be better integrated with other solutions that we have."

"The reporting is a bit cumbersome."

"The reports are okay, but the interface is a bit difficult to navigate in some cases."

"Tenable Nessus application device assessment is one of the top tools. However, in the application security assessment, there are other tools that provide better, and more accurate findings."

"I think the reporting templates could be improved with Tenable Nessus."

"The inventory management function in this solution needs improvement."

"Multiple user access would be an area for improvement from a user-access perspective. A role-based access control feature would be great because at present, there is a limitation with only one account. If that account gets compromised or gets locked, then we will encounter problems."

"One significant drawback we encounter is the tool's tendency to flag patched packages incorrectly. For instance, if a package is patched by Debian maintainers but not updated to a major or minor version, Nessus may still flag it as vulnerable based on its database. This discrepancy leads to false alarms and requires our developers, system admins, and DevOps teams to address them."

Pricing and Cost Advice

Information not available

"It is scaled as you go. There are probably a certain number of scans per month, and there are tiers. If you're under a certain tier, it is free. The second level is pennies, and then all the way up to like a million. So, it has a tiered pricing program. They're pretty good with your initial scanning, and there is room to scale based on being affordable, but it is fairly cheap. There are no additional costs. They pretty much think about it as a pay-per-scan type model."

"The lowest cost would be around $10 for a few small accounts, however, for thousands of accounts, it could be around $5000 to $6000 dollars per month."

"The pricing is very transparent and clear."

"It's priced according to market standards for its services."

"We incurred a single cost for a perpetual license, although I cannot comment on the price as this is above my management level."

"The solution is worth the cost. It's a good investment."

"The price of Tenable Nessus could improve, it is expensive."

"Tenable Nessus needs to be licensed. We own a license for the security center and that license is charged by the number of IP addresses that you can scan. You're allowed to have as many scanners as you want and there's no license for the number of scanners. We have a bunch of Nessus scanners out there, and as long as we're comfortable with staying under that IP address limit, that's really all we have to be concerned about."

"The product pricing is dynamic and varies based on the specific needs of each project and customer."

"The price of the solution is reasonable."

"The is a free version of Tenable Nessus available."

"The price of Tenable Nessus is too expensive for each service center."
