Attack Surface Management

Ostorlab Agentic Attack Surface Management helps security teams autonomously discover, validate, monitor, and secure their entire external attack surface. Agentic, graph-based discovery continuously investigates relationships between domains, web applications, APIs, IPs, mobile apps, infrastructure, and third-party assets to uncover exposure that traditional list-based approaches may miss. AI agents validate ownership, remove duplicates and noise, enrich asset context, and prioritize findings based on exposure and business risk. Continuous monitoring detects newly exposed assets, configuration changes, and emerging vulnerabilities. When meaningful changes are identified, the platform automatically triggers security testing, validates the risk, and routes actionable findings to the appropriate owners. Teams gain a continuously updated, evidence-based view of their external exposure—without relying on manual asset inventories or repetitive triage.

Ceeyu

The Ceeyu SaaS platform periodically performs automated scans and risk analysis of the digital footprint of companies (aka Attack Surface Management or ASM) and their suppliers or partners (aka Third Party Risk Management). Because not all security risks can be identified in an automated manner, Ceeyu also offers the possibility to carry out questionnaire-based audits. This can be done by creating questionnaires tailored to the supplier, from a white sheet or starting from templates that Ceeyu makes available. The completion of the questionnaire by the supplier and the follow-up of the process by the customer is done in a secure environment on the same SaaS platform. This enables a simple, central follow-up, entirely online and without the intervention of third parties. The closed platform guarantees the confidentiality of the survey, since only authorized persons have access to the application.

CheckFix

CheckFix is an automated external security assessment for your company. It shows you what an attacker sees when they look at you from the outside, and it tells you what to fix first. You enter your domain. CheckFix discovers your subdomains and runs a 15-step external analysis covering mail security, TLS configuration, known vulnerabilities (CVEs), security headers and exposed internet-facing services. The result is an A–F rating, both overall and per category, plus a prioritized to-do list. Every finding shows where the problem sits and how urgent it is: immediate action, short, medium or long term. Your admin or IT service provider can work through the list directly. No consultant has to translate it first. Once the fixes are done, a recheck shows whether they worked. We built CheckFix on more than ten years of manual penetration testing at secinto in Austria. It automates the external part of that work. That way small and mid-sized companies can check their security regularly instead of once every few years. AI Pentest add-on The external scan shows you where the doors are. The AI Pentest add-on tries to open them. It starts from your CheckFix results. In the dashboard you select single hosts or your entire scope, and you book a package of runs. Our own pentest agent works through the targets on our in-house hardware. No third-party cloud AI is involved. One of our human pentesters verifies every finding before it appears in your dashboard. The built-in Report Builder produces everything from host-level detail reports to an executive summary. After you've patched, you can use your remaining runs for retests. You get real pentest depth at a fraction of the cost of a comparable manual test. Audit Mode Customers, auditors and regulators increasingly want proof, not just a score. Audit Mode turns your CheckFix results into an audit-ready document, generated straight from the dashboard. For each open finding you add a management response. You document which residual risks you accept and why, and you set an action plan that says what gets fixed by when. The result is the evidence auditors ask for under NIS2, DORA, ISO 27001 or TISAX. Who it's for CheckFix works for any organization with an internet presence. For SMEs, a website and a mail server are enough to get meaningful results. Larger companies and organizations subject to NIS2, DORA, ISO 27001 or TISAX use CheckFix as a regular external security assessment within their security program. Suppliers use it to prove their security to larger customers. API keys are available, so you can pull results into your GRC tool or other systems. All data is hosted in the EU.

Cye

Cye is an AI-native cyber exposure management platform that tells organizations how exposed they are in financial terms, what to fix first, and whether their security program is actually improving. Founded in 2012, Cye works with 500+ organizations globally and has quantified more than $20B in cyber exposure across over 1 million analyzed attack paths. Discover, map and quantify. Cye ingests findings from existing security tools, scanners and assessments in any format, and its AI maps assets to findings automatically. Deployment is agentless and non-disruptive. The platform correlates exploitable vulnerabilities with real threat-actor techniques (MITRE ATT&CK) and organizational gaps to build an attack graph of the routes an attacker would actually take to business-critical assets, then quantifies each route as cost of breach — so exposure is expressed in dollars rather than CVE counts and severity scores. Remediate, mitigate or accept. Cye ranks fixes by risk reduced per unit of cost and effort, filtered to the paths attackers can genuinely use, and surfaces choke points where a single fix closes many routes. Security leaders can make a defensible call on each exposure — remediate it, mitigate it, or knowingly accept it against the organization's risk appetite. Agentic AI across the workflow. The Cye AI Agent is connected to each customer's own environment data and answers plain-language questions about their specific exposure, then turns the answer into remediation steps. What-If analysis simulates a planned control, tool or investment against the live risk model before budget is committed, returning predicted posture improvement, quantified financial risk reduction and implementation effort. The agent builds optimized mitigation plans and generates editable, board-ready PowerPoint decks in minutes straight from the chat, built on the organization's own data. Agentic assessments validate outcomes before action, which is what makes trusted auto-remediation possible: Cye currently generates remediation scripts and tasks for cloud misconfigurations, with autonomous remediation extending across the attack surface. Track, benchmark and report. Exposure, maturity, likelihood and cost of breach are monitored continuously with full drill-down, benchmarked against industry peers, NIST CSF averages and the organization's own trend line. Group-level management covers multi-entity, multi-region and multilingual organizations from one view. Reported customer outcomes include 96% of business-critical attack routes blocked within six months, 88% reduction in remediation time following an incident, 95% of critical exposures clearly prioritized, and 87% of customers improving ROI on their security budget. Cye pairs the platform with expert security services — red and purple teaming, penetration testing, cloud and OT assessments, AI risk assessments, incident response and CISO advisory — with results feeding back into the platform for tracking and reporting. Certifications include ISO/IEC 27001:2022, SOC 2 Type II, ISO/IEC 42001:2023, CREST and GDPR.
