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.
John D'Arcy - PeerSpot reviewer
Automated vulnerability assessments continuously enhance security
The most valuable features probably are the ability to do automated vulnerability assessments, which it does with Amazon Inspector version two. It operates continuously, so as soon as resources are created, it scans them for vulnerabilities. This allows me to pinpoint potential security vulnerabilities and provide actionable recommendations relatively quickly. Larger enterprises usually use Inspector to gather all the vulnerabilities, the CVEs, across all accounts in an AWS organization. The enterprises I work for typically have many accounts in their organization, such as thousands of accounts where I am at the moment. It is a way to gather the vulnerabilities that are present on EC2 instances, container images, and Lambda functions.
NaySan @ Suraj Verma - PeerSpot reviewer
Provides actionable vulnerability insights and recommendations with notable efficiency
They may need to improve the portal refresh rate for Microsoft Defender Vulnerability Management because it takes time for recommendations to disappear after mitigation; sometimes, it takes one week, when it should ideally take only one to two hours. Overall, everything is good with Microsoft Defender Vulnerability Management, but the portal refresh rate can take up to seven days in some cases and three or four days in others to reflect changes.

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 has become an indispensable tool in our cybersecurity arsenal."
"Overall, we have seen about eighty-seven percent reduction of the number of vulnerabilities that require urgency to remediate, specifically the number of criticals."
"We saw benefits from Zafran Security almost immediately after deploying it."
"Zafran is an excellent tool."
"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 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 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."
"The most valuable feature of Amazon Inspector is the categorization of findings, which filters vulnerabilities by instance, container image, container repository, and Lambda function."
"The automated vulnerability detection aspect is most valuable."
"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."
"Amazon Inspector is highly stable, rated ten out of ten, and this stability impacts business security and administration positively."
"Overall, I would rate Microsoft Defender Vulnerability Management a nine out of ten."
"The product's stability is very high...The scalability of the product is amazing."
"Microsoft Defender Vulnerability Management provides regular advisories and recommendations that help improve our security posture."
"The main advantage of Microsoft Defender Vulnerability Management is that it can locate and prevent most threats even when the endpoints are not connected to the corporate network, as long as the internet is available."
"The integration with SIEM is the best, specifically the native integration with Microsoft SIEM."
"Microsoft Defender Vulnerability Management is versatile and assesses vulnerabilities, providing detailed information on CVEs, their categories, and exploit statuses."
"A valuable feature is the ease of management and integration with Microsoft products."
"The product’s most valuable features are compliance, recommendations, and inventories."
 

Cons

"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 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."
"One area for improvement in Amazon Inspector is the automation aspect."
"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."
"It has automated vulnerability assessment, yet I seek more flexibility in defining custom vulnerability checks tailored to my needs, which is more difficult."
"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."
"There is room for improvement in the scanning capabilities. I'd like to see broader coverage in terms of the vulnerabilities detected."
"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."
"There are challenges associated with the interdependencies in AWS services, like requiring an Active Directory for other services, resulting in additional charges."
"The product is not stable; it is very resource-intensive, consuming a lot of memory and CPU, which makes it slow."
"The constant changes in the product configuration or the console setup can sometimes be challenging."
"The worst aspect is the refresh rate of the dashboard. A vulnerability I patch within 15 minutes takes 24 additional hours for an update."
"The general support could be improved."
"Integration can be improved."
"There should be risk scoring added to Microsoft Defender Vulnerability Management; specifically, they call it quantification of the risk."
"The technical support takes too much time to resolve tickets."
"Regarding Microsoft's technical support, I would rate it a three out of ten; they could be more responsive and knowledgeable."
 

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."
"It's priced according to market standards for its services."
"The pricing is very transparent and clear."
"The product’s pricing is medium."
"The tool is a bit costly."
"The licensing costs are reasonable."
"I rate the product's price a three on a scale of one to ten, where one is a low price, and ten is a high price."
"The licensing model follows a per-user per-month structure."
