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.

Global Chief Information Security Officer at Barry-Wehmiller

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.

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The user interface of Tenable Nessus feels outdated and could be more user-friendly.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

"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."

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

"One of the top things we're interested in is cloud protection."

"All the features within the XDR are valuable as a whole for our organization."

"Incident response is one of the key areas where the solution has been very useful. Whenever there is an incident, instead of being reactive, the government is now able to quickly gain the data that it needs to see what its end agency is also seeing and partner with them in real-time to look at the same data and to collaborate where needed, empowering the agency to be able to do their job."

"SentinelOne enhances our customers' risk management."

"The XDR capabilities are very good."

"Having high visibility into all of our network concerns and a customizable UI are the most valuable features."

"The threat detection capability is the most valuable feature."

"The incident and threat logs are great."

More SentinelOne Singularity Identity pros

"Out of the box, the product works well for us, so it's not a tool that we need to customize very much."

"The scanning and reporting features are the most valuable aspects of Tenable Nessus."

"The most valuable feature of Tenable Nessus is the GUI and user-friendliness. Additionally, the environment is easy to work with."

"Tenable Nessus has provided increased visibility across the organization's servers."

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

"We have done code scanning for a long period because as a company, we do DevOps as part of our development life cycle."

"The solution is very stable."

"The solution is the most dynamic one I have seen thus far."

More Tenable Nessus pros

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."

"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."

"Sometimes I get kicked out of the console. I don't know why."

"Support could be faster. They need a faster response time."

"The policies could be more precise, and Singularity should use more templates like alternative solutions have. Endpoint management is poor. We cannot manage individual endpoints and must rely on policies, exclusions, or block lists to apply settings to a group instead of the individual agent. If I have to make settings for one computer, I need to create a group, apply the configuration, and move the agent there. It's challenging to manage endpoints that way."

"The resolution turnaround from SentinelOne Singularity Identity's support should be improved."

"SentinelOne Singularity Identity could be more user-friendly."

"I don't like SentinelOne's reporting tools. Their reports seem fine theoretically, but the issue is the sample size. For example, it will report that there were four incidents, and that equals 25 percent fewer incidents compared to the previous months. It would be a great improvement if I could expand the range to see reports for the last six months, but it's always one month. That would be an easy thing for them to resolve."

"The solution's query resolution time could be reduced further, and a faster resolution could be provided."

"We haven't received the expected support whenever we've had questions."

More SentinelOne Singularity Identity cons

"They should try to create an all-in-one solution."

"Model OS costs (and its segregation schema for individual modules)."

"I would like to see an improvement in the ranking of high, medium and low vulnerability."

"In terms of what could be improved, I would say its reporting portion."

"Online learning could be a bit better."

"Technically, it is an excellent and the best solution available in Libya. My only concern is related to its pricing. They are an emerging company in Libya, and they need to put in some effort to provide us with very good prices so that customers can go with the best solution. Chinese companies are getting into the market here, and they're providing very cheap solutions."

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

"Lacks some penetration testing-related services."

More Tenable Nessus cons

Pricing and Cost Advice

Information not available

"The price is affordable."

"SentinelOne Singularity Identity's pricing is cheaper than CrowdStrike and is really good."

"The pricing is a bit high."

"The price of SentinelOne Singularity Identity is relatively high, but it offers numerous features and capabilities that make it well worth the investment."

"Compared to competitors, it's well-priced for the quality offered, and I don't see anyone surpassing them in that regard."

"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."

"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."

"Its price is a little bit high. It is a nice product, but it comes at a cost. Compared to other products, it is not cheap, but you sometimes have to pay for the value you get. It is not cheap, but it is worth it."

More SentinelOne Singularity Identity pricing and cost advice

"The price of the solution is reasonable."

"In general, it is extremely expensive."

"While Tenable Nessus is a good enterprise solution, the high price would likely make it prohibitive to smaller organizations."

"Its pricing is great and can't be improved. It is very cheap. It is less than 2,000 pounds a license, and you can't really ask for more. It has unlimited IPs and unlimited scans. There are no particular pricing constraints. The only additional cost is the inherent cost of the people to actually review the actual scans."

"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."

"The solution has a single price for unlimited assets."

"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."

Zafran Security

Singularity Identity, a component of the Singularity platform, provides threat detection & response (ITDR) capabilities to defend Active Directory and domain-joined endpoints in real-time from adversaries aiming to gain persistent, elevated privilege and move covertly. Singularity Identity provides actionable, high-fidelity insight as attacks emerge from managed and unmanaged devices. It detects identity misuse and reconnaissance activity happening within endpoint processes targeting critical domain servers, service accounts, local credentials, local data, network data, and cloud data. On-agent cloaking and deception techniques slow the adversary down while providing situational awareness and halting adversarial attempts at lateral movement. Singularity Identity helps you detect and respond to identity-based attacks, providing early warning while misdirecting them away from production assets.

Singularity Identity’s primary use case is to protect credential data and disrupt identity-based attacks. The most valuable function of Singularity Identity is its ability to misdirect attackers by providing deceptive data to identity-based recon attacks. Additionally, it can hide and deny access to locally stored credentials or identity data on Active Directory domain controllers.

Singularity Identity also provides rapid detection and respond to identity attacks, capturing attack activity and feeding it directly to the Singularity platform’s Security DataLake for enterprise-wide analysis and response.

By implementing Singularity Identity, organizations benefit from enhanced security, reduced credential-related risks, and improved user productivity. It detects and responds to identity-based attacks, ensuring only authorized individuals can access critical identity data. With its cloaking capabilities to hide identity stored locally on endpoints or in the identity infrastructure and it’s ability to provide decoy results to identity-based attacks, organizations can effectively secure their sensitive or privileged identities, resulting in improved overall identity security.
