What it sells: Zafran Security

What Zafran Platform does[2]
The Zafran platform takes cloud and AppSec findings from Wiz, Palo Alto Networks, Upwind, AWS and Snyk, and on-prem findings from Tenable, Qualys and Rapid7. Zafran applies a customer's own risk context to reveal which vulnerabilities are exploitable in its environment. Zafran uses existing security controls to show how to reduce exploitability across the environment. Zafran auto-assigns fixes to the right owner in Jira, Slack and ServiceNow.
What RemOps does[1][2]
RemOps uses generative AI to consolidate overlapping remediation tasks and create a clear get-well plan. RemOps routes work to the right owners through existing ticketing platforms.
What Zero Day Agent does[6]
Zafran's Zero Day Agent matches a flaw to a customer's live software inventory, showing which assets run the vulnerable version, which are reachable from the internet, and which are blocked by a live control. Zafran autonomously identifies which assets new threats affect every day, using threat intelligence matched against SBOM data.
What Exposure Graph does[2][7]
Zafran's Exposure Graph weighs what's running and reachable, exploited in the wild, unprotected by controls, and critical to the business. Zafran's exposure graph unifies findings from continuous detection, cloud, AppSec and on-prem scanners, adds risk context, and maps each exposure.

About VulnCheck

VulnCheck sells a Cyber Threat Intelligence platform that provides exploit and vulnerability intelligence for prioritizing and remediating vulnerabilities. VulnCheck's platform supports prioritizing vulnerabilities based on the threat environment and deferring vulnerabilities that do not matter.[5]

VulnCheck defines TTE (Time-to-Exploitation) as the gap between CVE disclosure and confirmed exploitation. VulnCheck also provides real-time alerting of changes in vulnerabilities, so that customers can take action before attacks start.[5]

VulnCheck offers Exploit & Vulnerability Intelligence for decisions on which vulnerabilities need immediate remediation. VulnCheck provides early access to new vulnerability information not found in the NVD, along with dozens of unique fields. VulnCheck provides an exploitation timeline covering when a vulnerability was first disclosed, when evidence of exploitation was first discovered and when the vulnerability was remediated. VulnCheck directs remediation effort to vulnerabilities that are being actively exploited in the wild.[5][15]

VulnCheck develops exploit PoCs, packet captures, and Suricata signatures in house to defend against initial access vulnerabilities. VulnCheck provides data from globally deployed Internet sensors that reveals the first signs of vulnerability exploitation. VulnCheck states that when it is given a CVE, it tells the customer every vulnerable host on the internet right now. VulnCheck for Government includes features, functionality and data available only to VulnCheck's Government partners.[5][7][8][16]

VulnCheck's Initial Access Intelligence team has detailed an unauthenticated pre-auth remote root RCE chain in Control Web Panel. VulnCheck reports third party vulnerabilities.[1][5][17]
