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.
OndrejKOVAC - PeerSpot reviewer
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.
Sumit Bhanwala - PeerSpot reviewer
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 saw benefits from Zafran Security almost immediately after deploying it."
"We are able to see the real risk of a vulnerability on our environment with our security tools."
"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."
"Zafran is an excellent tool."
"The most valuable features of Tenable SC are scanning, reporting, dashboards, and automation."
"The initial setup process is simple."
"It's a very useful tool."
"We use Tenable to scan all of our environments and plugins for vulnerabilities. Tenable helps us discover network vulnerabilities to threats and piracy."
"The valauble feature is compliance reporting system."
"Tenable SC's most valuable features are the low number of false positives and the strong capability of providing prioritization for the vulnerabilities detected."
"I found the dashboard features very useful. It made it easy to track remediation progress. I could publish dashboards to remediation teams and track the progress on the dashboards."
"Tenable.sc's best features are the availability model, accident management, and scoring."
"This secure connection allows users to connect to the Zscaler VPN and access the resources on the office network, making it a highly valuable component of our system."
"It is a very scalable solution. Scalability-wise, I rate the solution a ten out of ten."
"It has some good data security and WIP features, providing secure Internet access."
"Zscaler Cloud DLP provides you with basic DLP features that you get out of the box such as keywords, regular expressions, and data identifiers, for example, your social security numbers, and credit card numbers, with everything built into the product, so you can directly use those features within the policies. You don't need to create it from scratch, and to me, this is the biggest benefit of Zscaler Cloud DLP. You have a lot of templates to choose from in the solution, rather than having to create templates from scratch or reinvent templates."
"The policies are very easy to implement."
"The scalability is pretty good."
"I like the web filtering capabilities."
"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."
 

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."
"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."
"The dashboarding and reporting functionality of Zafran Security is an area that definitely could use some improvements."
"It's important for Tenable to catch up on testing capabilities that are present in solutions like Qualys."
"The tool's initial configuration is not so easy."
"A good plugin editor would be a good additional option for the Security Center."
"The reporting side can be improved. The dashboards are nice, but exporting things out for reports for management was a little tough."
"I think the vendor training provided for Tenable.sc could be a lower price. It's quite expensive for the training."
"There's a lot of information being streamed out of the reports. What would be nice, and maybe we just haven't found it, would be more of an executive-type view. We still expect it to collect all this information, but we would like a feature that would allow us to show it to an executive or a director or someone like that and give them some type of high-level overview but not get into the nitty-gritty."
"The product could be user-friendly, and they could enhance the web application's security features."
"The solution should provide better web application features and support."
"Zscaler Private Access needs to improve its collaboration with applications without compromising security."
"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."
"Sometimes applications crash on some machines, and we’d like Zscaler to give us some information as to why that may have happened. We’d like more detailed reports."
"We have issues with the tool's maintenance and networking. It should be able to work in offline mode as well."
"The granularity in blocking is not sufficient, as new domains are automatically blocked for 30 days without further information."
"What could be improved in Zscaler Private Access is its notification. For example, if there's a speed issue, there should be a pop-up that alerts the user about it. If there is a network quality issue, for example, it isn't good enough to connect to, or the network quality is bad, there should be a notification from the solution. Zscaler Private Access also needs improvement in terms of its interface and security."
"While Zscaler supports client-initiated connections, it does not support server-initiated connections. This is a feature that Zscaler may consider adding in the future."
"The pre-defined dictionaries could be improved."
 

Pricing and Cost Advice

Information not available
"I rate the solution's price as seven on a scale of one to ten, where one is cheap and ten is expensive. The tool is quite expensive."
"I would rate the pricing a nine out of ten, where ten is expensive. It is the most expensive tool my company is using."
"We're a Fortune 500 company... our licensing costs [are] in the seven figures."
"It is slightly more expensive than other solutions in the same sphere."
"My company needs to make yearly payments towards the licensing costs. The pricing of the solution falls in the mid-range level, so it is not too expensive"
"The price can start at €10,000 ($13,000 USD) for between 500 and 1,000 assets, and the price can climb into the millions as more assets are added."
"It is a bit expensive. Everything is included in the license."
"Compared to other companies or other products it could maybe be a little bit less, but the price is okay. I would say it's not very expensive."
"It has been relatively reasonable for what it does. Some of the additional license costs based on the advanced next-generation firewall functions are quite high, and they should have certain features ready and available as a baseline rather than having to purchase additional licenses for it. Overall, the cost seems reasonable."
"My company is a Zscaler Private Access partner, so the customers pay for the license fees."
"Pricing for Zscaler Private Access is moderate. It's acceptable, though I can't give you the exact price currently. It's not too expensive, and on a scale of one to five, I would rate it a four out of five in terms of pricing."
"The solution has increased prices this year."
"Zscaler Cloud DLP is moderately priced. We pay around 2 million rupees per year."
"It is an auto-renewal subscription service."
"The pricing is expensive and on the higher end. Honestly, in my opinion, it is not worth the price."
"Zscaler CASB is an expensive solution."
