Censys offers an attack surface management platform that provides internet intelligence to security teams. The platform continuously scans the internet to discover and inventory internet-facing assets, giving organizations a complete view of their digital exposure. This helps users identify and remediate risks such as open ports, vulnerable software, and misconfigured devices. Customers include Global 2000 companies, government agencies, and security providers, and the service is sold on a subscription basis. Compared with competitors, Censys emphasizes ongoing, wide-scale internet reconnaissance to produce a comprehensive asset inventory and risk context, not just internal scans or point-in-time checks. The company’s goal is to help organizations manage exposure, reduce security risk, and improve threat detection by providing up-to-date visibility into their attack surface.

↓ -2%Censys, an internet intelligence company, reported record growth in the first half of 2026, driven by enterprise adoption of AI-enabled security workflows. The firm saw 400% growth in customers generating over $1 million in annual recurring revenue and 115% growth in Censys Platform customers. The company expanded internationally, with ARR growing 115% in Asia-Pacific and 82% in EMEA. Censys now operates in 13 countries, serving customers across 46 nations. Partner-sourced bookings grew 186%, with the company surpassing 200 global partners. New strategic partnerships include Tanium, whilst technology partners like Abstract and Swimlane released integrations with Censys. The company enhanced its platform with expanded DNS intelligence, broader protocol coverage, and new AI-native capabilities designed to accelerate security investigations and automate workflows.
Censys has expanded its Internet Map to include real-time DNS visibility, allowing security teams to understand Internet infrastructure through a single platform. The company now integrates domains, DNS records, IPs, hosts, services, and certificates in one unified view. The expansion enables analysts to pivot between name-based and IP-based infrastructure whilst tracking how it evolves over time. Security teams can use the platform across workflows including triage, investigation, threat hunting, and defence. Censys customers have already used the DNS capabilities to identify phishing campaigns. During a recent USPS-themed attack investigation, one malicious domain revealed hundreds of related phishing domains and broader campaign infrastructure, including historical DNS relationships no longer visible through live DNS. The unified platform aims to replace fragmented external intelligence tools with cohesive infrastructure mapping.
Censys, an Internet intelligence platform, has expanded into security operations, enabling organisations to integrate its intelligence across security workflows. The company introduced the Censys Enrichment API, allowing security teams to enrich alerts with real-time Internet context at scale. The expansion builds on recent innovations including risk scoring, adversary intelligence, AI-powered workflows, and integrations with SIEM, SOAR and threat intelligence platforms. Built on the Censys Internet Map, the platform provides continuously updated views of global Internet infrastructure to help security teams validate risks and prioritise responses. Censys customers have used the intelligence to identify emerging threats, including a previously undocumented Russian remote access framework and exposed AI infrastructure. The Ann Arbor-based company serves governments, Fortune 500 companies and security providers globally.
Censys has appointed Sandy Dlugozima as Senior Enterprise Account Executive for the Southeast US to help organisations modernise security operations with real-time Internet intelligence. The company aims to address a critical gap in external context that limits detection, investigation and response capabilities. Security teams modernising their SOCs with AI and automation often have strong internal visibility but lack external context needed to defend against modern threats. This causes AI initiatives to operate on stale, inaccurate data with incomplete external visibility, impacting their ability to deliver expected improvements. Dlugozima will work with customers and partners to integrate Censys' real-time Internet intelligence with SIEM, SOAR and partner-delivered services, providing security teams with a more complete operational view. The company emphasises that without strong external data foundations, automation simply scales incorrect outcomes.
Tanium has partnered with Censys to deliver a unified approach to exposure management combining internal and external attack surface visibility. The collaboration integrates Tanium's real-time endpoint intelligence with Censys' global internet infrastructure mapping to help organisations identify, prioritise and remediate security risks. The partnership addresses the growing need for continuous exposure management as AI accelerates vulnerability discovery and exploitation. Tanium enables real-time vulnerability scanning and remediation across endpoints, whilst Censys provides visibility into external internet exposures and attacker-controlled assets. The combined solution aims to eliminate silos between internal and external security views, enabling faster risk-prioritised remediation without manual handoffs. Both platforms focus on data quality and real-time intelligence to help security teams move from insight to action more efficiently.
