About NopSec

NopSec sells a Cyber Threat Exposure Management (CTEM) platform and penetration testing services.[1][2][3]

NopSec addresses teams that struggle to understand and remediate the vulnerabilities that matter to their business using a mix of spreadsheets. NopSec serves the RBVM needs of CISOs and Vulnerability Management teams.[2][4]

The NopSec platform aggregates vulnerability prioritization, remediation automation and performance reporting into one centralized platform. NopSec integrates with infrastructure scanners, cloud asset scanners, application scanners (SAST and DAST) and Configuration Management Databases (CMDBs). NopSec UVRM integrates with over 50 threat intelligence and asset data technologies to assess risk, prioritize remediations and report on progress. Bi-directional syncing between NopSec and vulnerability scanners ensures security tools report the same status.[1][2][5][6]

NopSec uses a patented machine-learning algorithm to surface infrastructure, application and cloud/container vulnerabilities most likely to be weaponized. NopSec prioritizes vulnerabilities associated with malware and exploit kits, not just vulnerabilities identified with exploits. The NopSec platform aggregates application and infrastructure vulnerability data. NopSec attack path mapping lets Security teams visually validate the effectiveness of their controls and the effects of their potential remediations on their network.[5][9]

NopSec provides full-stack reporting that puts application vulnerabilities next to infrastructure vulnerabilities. NopSec enables Security teams to benchmark progress, quantify risk remediation and articulate risk by business line.[5]

NopSec has performed manual penetration testing and red-teaming engagements across infrastructure, applications, wireless, mobile, social engineering and VoIP since 2008. NopSec in-house security experts simulate attack scenarios on a customer environment to help identify critical vulnerabilities before they are weaponized. NopSec evaluates exploitable areas of risk in infrastructure, applications and employees. NopSec services are custom scoped and custom quoted because no two environments are exactly the same.[7][8]

NopSec runs either agent-deployed or traditional-schedule scans. NopSec reports on risk posture and progress in the customer's UVRM instance.[9]

NopSec's security research team simulates real-world attacks against AI-powered applications, LLM integrations and agentic infrastructure to find exploitable weaknesses. NopSec tests applications that use retrieval-augmented generation for adversarial content injected into the knowledge base or retrieved documents.[3]

Cisco announced end-of-life for Kenna Security in December 2025. NopSec created a dedicated program specifically for Kenna customers. NopSec's JumpStart Program includes dedicated migration specialists. NopSec is scanner-agnostic and integrates with Tenable, Qualys, Rapid7, CrowdStrike, Defender, AWS Security Hub, Azure Security Center and many other sources.[10]

NopSec was founded by white hat hackers aiming to help companies improve their cybersecurity from attacks. NopSec follows the NIST Cybersecurity Framework with layered security controls to help identify, prevent, detect and respond to security incidents.[1][2][3][9][10][12]
