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.

Empower clients with risk-based vulnerability management through continuous workflow and valuable insights

Tenable Security Center could improve by implementing more dynamic data displays and translating reports into European languages. This is especially relevant in Central Eastern Europe, where clients often require reports in local languages. Additionally, the licensing model could be more flexible for managed security providers, similar to a pay-as-you-go model.

Cloud-based platform simplifies device and data center management

I find it to be good. The solution is cloud-based with the latest inspection engines, which I find to be amazing. We are less dependent on data centers and device management, which reduces our efforts significantly. It improves our device management, data center management, and updating devices. We need fewer engineers for this management, and it reduces time and efforts for data center management, device upgrades, and IT support.

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."

"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."

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

"Overall, I rate the solution 9.8 out of 10."

"It's a very useful tool."

"The most valuable features of Tenable SC are the reports and the dashboards."

"This product has the best results in terms of the lowest number of false-positives and false-negatives."

"It basically reviews our threat landscape vulnerability."

"Very customizable with a lot of templates."

"Has a great advanced scanning feature."

"One of the most valuable features is their distributed scan model for allotting engines to work together as a pool and handle multiple scans at once, across multiple environments. Automatic scanning distribution is a distinguishing feature of their toolset."

More Tenable Security Center pros

"The policies are very easy to implement."

"It is a stable solution."

"On DLP terms, Zscaler Cloud DLP ensures that data doesn't go outside of the organization. So on the network level, Zscaler does a pretty good job."

"Users get direct secure access to applications over the internet."

"Sandboxing, DLP, and SSL inspection engine are the most valuable features of Zscaler SASE."

"It is a very scalable solution. Scalability-wise, I rate the solution a ten out of ten."

"The most valuable features of this solution are the CASB solutions, which is protecting their Office 365."

"I find all Zscaler Private Access features valuable because each replaces flawed technologies, such as EPAs being replacements for VPN and PR as a replacement for PAM, so I can't mention only one valuable feature. Overall, Zscaler Private Access is a good solution."

More Zscaler Zero Trust Exchange Platform 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."

"In terms of configuration, there is some level of flexibility that we are not able to achieve."

"We experienced some difficulties with the solution’s support."

"The reporting side can be improved. The dashboards are nice, but exporting things out for reports for management was a little tough."

"It's important for Tenable to catch up on testing capabilities that are present in solutions like Qualys."

"Additional costs are associated with using the solution, as additional scanners are required for different endpoints connected to the Tenable Security Center. If Tenable Security Center could extract information from these scanners automatically rather than manually, it would enhance user-friendliness for customers."

"Security can always be improved."

"The solution's user interface has some issues."

"The biggest issue I have with the solution is when I'm using the scanning it picks up the original DNS of that device. That means, before we image it and actually change the DNS to something within our company structure, it'll just be random numbers and letters and Tenable will stick to that DNS for a long time."

More Tenable Security Center cons

"The area that requires improvement is their support. The current support is lacking."

"It has massive room for improvement. The Zscaler product itself is okay, but it doesn't give enough granularity for us as an organization to stipulate rules or processes, especially for data-driven services. For instance, we can stick on SSL inspection, but it's just a click box. It doesn't allow us to go any further into the detail of the SSL inspection. We also can't pull it out without having an additional logging server. It just doesn't give us enough granularity. They should give us more control over the interfaces because it is all backend. They weren't very open to discussing their backend architecture with us in terms of their own data centers. They can maybe a little bit more open about what components are there and how the backend infrastructure works alongside Zscaler. Its licensing can be better. Some of the additional licensing costs are quite high, and they should have certain features ready and available as a baseline rather than having to purchase additional licenses for it. Their support should also be improved. I initially had a consultant from Zscaler for its deployment, but the support that I had throughout the deployment of the project wasn't the best."

"Zscaler CASB breaks down at times."

"User management can be improved."

"It would be better if the Zscaler Private Access team made it easier for people to find subscriptions on the portal, mainly information on what my customers subscribed to or the type of licenses purchased."

"We'd like to have two-factor authentication that is quite simple."

"The only issue with Zscaler Cloud DLP is that it only gives you DLP protection from web traffic, which is flowing out, while a full-blown DLP solution such as Forcepoint or Symantec gives you DLP coverage for multiple channels. Zscaler Cloud DLP doesn't give you coverage for email, fax, and USB channels, and this is the only challenge or room for improvement in the solution. It's just an extension on top of what you're buying on the proxy, so it's just an added layer, and it doesn't cover DLP on a very broad level. I'm unsure if Zcaler is in the business of competing with a full-blown DLP solution, and if there's a plan to expand the features of Zscaler Cloud DLP beyond the web channel because you'll have to deploy a full-blown agent for it. I'm unsure if this is on the cards because the solution is just an added layer that you get with your proxy. I've asked the Zcaler team whether there's a plan to go full DLP in the future, but I didn't get a positive response. There isn't any feature I'd like added to Zscaler Cloud DLP currently, because anything you could think of that should be in cloud or SaaS solutions is already there, except for machine learning, as it's the only functionality that seems to be lacking in the solution. Machine learning is an additional policy available in other DLP solutions in the market, but my team didn't find it in Zscaler Cloud DLP."

"The connectivity monitoring part should be included in the core license without any extra charges."
