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.
Roftiel Constantine - PeerSpot reviewer
Provides proactive threat remediation, reduces alert volume, and enhances incident response capabilities
During our pre-purchase evaluation of SentinelOne's EDR capabilities three years ago, we were consistently impressed by the positive relationships customers reported having with SentinelOne's engineers, sales teams, and customer success managers. These strong relationships, evident in the customers' unsolicited feedback, highlighted the "soft skills" and intangible qualities that SentinelOne possessed. This positive customer experience has been mirrored in our own interactions with them. Their responsiveness to our needs, particularly when addressing a couple of challenges we faced, has been excellent. They proactively scheduled weekly meetings to demonstrate their commitment to resolving our issues, a customer-centric approach I admire. SentinelOne's dedication to customer service, including their rapid technology updates and responsiveness to our suggestions, has been crucial to our success in protecting our organization. Their ability to quickly incorporate our needs into new releases is truly impressive and sets them apart. Overall, I highly recommend SentinelOne based on our positive interactions across all levels of their organization.
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The user interface of Tenable Nessus feels outdated and could be more user-friendly.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.

Pros

"Zafran has become an indispensable tool in our cybersecurity arsenal."
"We are able to see the real risk of a vulnerability on our environment with our security tools."
"Zafran is an excellent tool."
"I like the detection and protection features. We don't need to do anything, and it will alert us when the mitigation is not successful. We only need to target those endpoints. Otherwise, we don't have to do anything about that."
"The response is a valuable aspect of SentinelOne."
"SentinelOne stands out due to its AI capabilities, which lead to excellent prevention."
"The XDR capabilities are very good."
"All the features within the XDR are valuable as a whole for our organization."
"The AI provides a futuristic ML model. That helps a lot when it comes to shifting security approaches and hep better forecast attacks."
"The effectiveness of their AI and behavioral analysis helps mitigate zero-day activities and detect new threats."
"Behind the scenes, SentinelOne has real people who evaluate problems and mark them as false positives. That's what I find most helpful."
"The results are not that bad, but the key selling point is that it is an affordable tool set."
"The ease of use is the primary valuable feature. This specific version is very straightforward. I like the ability to modify it and configure it based on the different policies."
"Nessus gives me a good preview of vulnerabilities and good suggestions for remediation. It's easy to find a description of a given vulnerability and solutions for it."
"The support has been really cooperative."
"It provides multiple recommendations towards the remedy of vulnerabilities."
"Tenable Nessus streamlines the process of scanning for our organization."
"It gives a holistic view of your entire environment."
"The solution is the most dynamic one I have seen thus far."
 

Cons

"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."
"Our engineers are dealing with issues to add exclusions to the antivirus for custom applications."
"The resolution turnaround from SentinelOne Singularity Identity's support should be improved."
"Sometimes I get kicked out of the console. I don't know why."
"The solution's query resolution time could be reduced further, and a faster resolution could be provided."
"We've brought three critical items to their attention regarding vulnerability management."
"The UI can be more user-friendly."
"Support could be faster. They need a faster response time."
"Agent connectivity can be improved, as it is one aspect of the product with certain shortcomings."
"Tenable Nessus could improve the reporting."
"In terms of what could be improved, I would say its reporting portion."
"They should improve the I/O reporting and the customized spreadsheet export feature."
"The report for counters is too simple and would be improved by a dashboard."
"We'd like to see the solution embrace more user-friendliness."
"The problems I faced with Tenable Nessus were related to its dashboard's customization capabilities and its ability to provide data to third-party sources."
"Lacks some penetration testing-related services."
"I would like to see an improvement in the ranking of high, medium and low vulnerability."
 

Pricing and Cost Advice

Information not available
"Ideally, I would like SentinelOne to lower their prices a little bit."
"The price of SentinelOne Singularity Identity is relatively high, but it offers numerous features and capabilities that make it well worth the investment."
"There is a need to make yearly payments towards the licensing charges associated with the product...I think the prices associated with the product are okay and it is not too expensive."
"Compared to competitors, it's well-priced for the quality offered, and I don't see anyone surpassing them in that regard."
"As a SentinelOne partner, we offer competitive pricing on comprehensive packages that include the SentinelOne license, our management services, and a proof-of-concept to ensure the technology meets your needs."
"SentinelOne Singularity Identity's pricing is cheaper than CrowdStrike and is really good."
"The pricing is a bit high."
"The price is affordable."
"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 newer tools are quite pricey. There is a case of some fine tuning that can be done in terms of licensing. The IP based licensing that is offered makes the tool very expensive. If they want the IT industry to adopt it, the price should be looked at."
"I think the price is fairly affordable. It provides a license that is fair."
"The price of the solution is reasonable."
"Cost-wise, it's an affordable tool."
"The price is okay. I would give it a seven out of ten, where one is cheap and ten is expensive."
"While Tenable Nessus is a good enterprise solution, the high price would likely make it prohibitive to smaller organizations."
"Its price is high for Libya. The companies here in Libya don't have the awareness of and a good budget for cybersecurity services. If you want them to go for a product, you need to provide something different. This differentiation is related to the price. They should give about 40% to 45% discount per person on the current cost."
