About Attaxion

Attaxion sells a platform that maps an organization's entire attack surface, identifies critical vulnerabilities and supports remediation with guided next steps and workflows. Attaxion is an EASM platform with asset discovery techniques. Attaxion discovers assets both known and unknown to the organization using it. In addition to the assets a customer specifies, Attaxion discovers other assets on the external attack surface and scans them for vulnerabilities.[3][4][6][7]

Attaxion LiveSight shows what is exposed across an attack surface and who is actively communicating with the network in near real time. Attaxion has a free Community Edition tier, to which an account is downgraded after its trial ends. On the Community Edition tier, Attaxion runs discovery and vulnerability scans on a monthly basis. On the Community Edition tier, the number of scanned assets is reduced to 40, and only 50% of them can be viewed.[5][6]

Attaxion runs fully automated security testing for web apps across an organization's entire external attack surface. Attaxion discovers web applications across the entire external attack surface, including ones the organization did not know about or forgot about. Attaxion finds issues in web applications such as vulnerable third-party technology, XSS and open ports. Attaxion continuously analyzes web applications and finds vulnerabilities and misconfigurations without causing disruptions. Attaxion builds and maintains an inventory of third-party technologies used across web apps, highlighting technology versions and related assets that pose higher risks. Attaxion can generate reports for individual web apps and for an entire external attack surface. Attaxion provides detailed reports for stakeholders on each web app an organization manages.[2][5][7]

Attaxion uses EPSS and CISA KEV data to help prioritize critical issues that are more likely to be exploited or known to be exploited in the wild. The vulnerability catalog of Attaxion is regularly updated with new entries, and Attaxion continuously runs scans across web applications to find assets vulnerable to emerging threats. Attaxion creates support tickets with information about issues.[7]

Attaxion identifies, assesses and continuously monitors for new third-party technologies and associated risks. Attaxion provides insights into the security posture and inherited cyber risks of target candidates. Attaxion is used to eliminate potential compliance issues by ensuring all external assets are cataloged and scanned for vulnerabilities.[5]

A regional bank with about $80 billion in assets relied on Attaxion to switch to risk-based vulnerability management (RBVM). The regional bank serves users across North America, focuses on commercial banking and offers financial advisory and investment services. The regional bank operates in a heavily regulated industry and maintains compliance with requirements such as the Gramm-Leach-Bliley Act and PCI DSS. The infrastructure security team at the regional bank is short-handed. The regional bank moved from traditional vulnerability management to risk-based vulnerability management with automatic asset discovery, to cover its web-facing infrastructure and prioritize vulnerabilities based on exploitability. The regional bank chose the Attaxion EASM platform to provide the necessary data and enable RBVM. Using varied cyber reconnaissance techniques, Attaxion enabled the bank to identify and secure previously unknown assets that were putting it at risk of non-compliance. Some of the previously unknown assets at the regional bank were not in scope for penetration tests and would have remained shadow IT after the yearly pentesting exercise. For the regional bank, Attaxion goes beyond CVSS-based risk scoring and factors EPSS and CISA KEV data into vulnerability prioritization.[1][4][5]

Totalmobile gained attack surface visibility, uncovered shadow IT and implemented EASM with Attaxion. Pollysoft automated visibility over its external assets and critical vulnerabilities. Rand Machine Products uses automated asset discovery with Attaxion for remediation. PEAK Wind worked toward NIS2 compliance with continuous external visibility. A small security team scans servers and web apps using the attack surface management of Attaxion.[1][5]

Attaxion commonly works with larger businesses with an extensive infrastructure. Attaxion accounts can be upgraded from within the app, and the Attaxion sales team sets up custom Enterprise plans.[1][5][6]
