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.

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.

Has enabled me to reduce false positives and perform deep credential auditing with seamless integrations

I mostly use the configuration audit feature for the audit configuration as a scan policy, and I will use it for credential audit, which helps me scan credentials access such as local administrator or root access, performing a deeper and more accurate check of local configuration settings and file systems, making it a highly recommended feature. Regarding integration capabilities, we can integrate Tenable Nessus with SIM tools such as Splunk, IBM QRadar, and Azure Sentinel, as well as with ticketing systems such as ServiceNow, Jira, and Slack. There is no complexity as it is very easy to integrate everything. In terms of the reporting feature, while vulnerability scanning can throw some false positives, Tenable Nessus has very few, achieving a reduction of 75% to 80% false positives with manual analysis needed. We can generate standard Nessus reports that typically include host summaries and vulnerabilities by host and plugin, alongside solutions and remediation recommendations. The main benefits I get from Tenable Nessus are complete asset inventory and comprehensive attack surface management, allowing us to prioritize vulnerabilities based on risk, focusing on true risk and threat path analysis.

More Tenable Nessus pros

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."

"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."

"A lot of those features came from an acquisition of a different company."

"The root cause of automation could be better."

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

"Agent connectivity can be improved, as it is one aspect of the product with certain shortcomings."

"There is a clear roadmap for improvements, including enhancing capabilities with AI and seamless functionality in an MSP model for deeper visibility across multiple agencies. Further development is anticipated to continue enhancing the solution."

"Our company has different locations, such as Sunbury, Oklahoma, and Alabama. I have my devices by location, and I have not found a way to choose all the endpoints and then push the update automatically. I have been doing it one by one."

"The primary reason for this discontent is that we frequently encounter performance issues with our servers."

More SentinelOne Singularity Identity cons

"We feel the solution's technical support to be very bad."

"There could be an integration between Tenable Nessus and other Tenable products. It will help us manage all the solutions using one dashboard."

"The reporting could be improved. The reporting in Rapid7 is much better."

"Multiple user access would be an area for improvement from a user-access perspective. A role-based access control feature would be great because at present, there is a limitation with only one account. If that account gets compromised or gets locked, then we will encounter problems."

"The product must be more comprehensive."

"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."

"Consumes more system resources when it's running."

"The report for counters is too simple and would be improved by a dashboard."

More Tenable Nessus cons

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.
