Company profile
researched Aug 2026X80 Security is a Paris, France cybersecurity company that provides attack surface management from an "attacker's-eye" perspective. Its platform maps an organization's exposure across three axes: people (leaked credentials, infostealer logs, exposed staff data used in social engineering), systems (exposed services, misconfigurations, vulnerable software and forgotten assets) and third parties (vendors, sub-processors and supply-chain partners). Rather than ranking findings by a generic severity score, the company orders them by attacker economics β which weaknesses are cheapest to exploit and most profitable to monetize β and presents the full kill chain from initial entry through escalation to the attacker's objective, such as data theft, extortion or fraud.
The product is delivered outside-in with no agents or integrations required, drawing on a dark-net scanner and intelligence about people and companies. Prospects can run a free systems-axis scan that produces a preview report in minutes, with the complete report β adding the people and third-party axes, remediation steps for each finding and the full kill chain β delivered by email. Alongside the self-serve platform, X80 operates an offensive-security team that performs penetration tests for SOC 2 and ISO 27001, code audits and red-team engagements; the company frames compliance as a by-product of the work rather than its purpose.
Earlier public directory descriptions characterize the company in terms of a simulation environment generating large volumes of synthetic threats to automatically produce defenses for fast-growing startups, positioning it as a substitute for hiring in-house cyber threat analysts. A Gust profile describes the company as "Automated Cyber Defence creation through Self-Learning from Generation of Threats in a Simulation Environment," at prototype-ready stage with three employees and an LLC incorporation type in Paris (postcode 75000)."]
Founding story
Company materials state X80 Security was founded on the question "what's in it for the attacker?", reasoning that both criminal crews and state-backed operators behave like a business β investing time, money and tooling and acting only when the payoff justifies the effort β and that security should therefore be analyzed as an economic decision. Public directories give conflicting founding years: EU-Startups lists 2020.
Business model
Two complementary lines: a self-serve subscription platform sold for a stated "accessible monthly price" that continuously surfaces an organization's exposure, and human-delivered offensive-security services including penetration testing (for SOC 2 and ISO 27001 needs), code audits and red-team engagements. A free, no-access attack surface report serves as the entry point.
Recurring monthly subscription for the continuous exposure-monitoring platform, plus project-based fees for offensive-security engagements (pen tests, code audits, red teaming). Specific pricing is not disclosed in the sources.
Traction
Limited public traction data. Sources indicate three employees, prototype-ready stage and no announced funding. No customer counts, revenue figures or named references are disclosed.
Latest developments
The current website markets a live free "attacker's-eye" report with a systems-axis scanner preview and an email-delivered full report covering people and third-party axes, remediation steps and the kill chain, alongside a services offering covering SOC 2/ISO 27001 pen testing, code audits and red-team engagements.
βΈFull profile β market position, technology, go-to-market, geography, history, risks & controversies
Market position
Small, early-stage vendor in the attack surface management and offensive security segment. Public directories list no announced funding and three employees, with the Gust profile marking the stage as prototype ready; the company is listed in the Entrepreneurs First portfolio and in the EU-Startups database under France with tags including cloud security, cyber security and SaaS.
Prioritization by attacker economics/ROI rather than generic vulnerability scores, explicit end-to-end kill-chain mapping instead of isolated vulnerability lists, coverage of people and third-party exposure alongside systems, and a zero-access outside-in approach; the combination of a low-cost self-serve platform with an in-house offensive-security team is also positioned as a distinguishing element.
Technology
Outside-in reconnaissance requiring no customer access, combining a dark-net scanner with intelligence on people and companies to detect leaked credentials and infostealer logs, exposed services, misconfigurations, vulnerable software, unknown assets and third-party/supply-chain exposure. Findings are scored by exploitation cost versus monetization payoff (return on investment) and assembled into kill-chain paths spanning entry, escalation and objective. Directory material additionally describes a simulation environment generating on the order of 100 million threats per day to automatically produce corresponding defenses.
Go-to-market
Product-led self-serve acquisition: a free systems-axis scan runs in minutes with no access, agents or integrations, and the full multi-axis report is emailed after a request, creating a lead capture path into the paid platform and the services team.
Startups and small security teams without large in-house security budgets; company materials state the mission is to make attacker-grade security reachable for a startup rather than a privilege of organizations with a large security team and six-figure budget. Directory copy references fast-growing startups and founders who would otherwise hire cyber threat analysts.
Geography
Headquartered in Paris, France (postcode 75000 per the Gust listing); listed under France in the EU-Startups database and under Paris in the Entrepreneurs First portfolio taxonomy. No other offices are indicated; the product is delivered remotely as an outside-in scan.
History
Public listings describe an earlier positioning around an automated threat-simulation environment that generated defenses for startups, while the current website presents a broader outside-in attack surface management product across people, systems and third parties plus an offensive-security services arm. The EU-Startups directory records no announced funding, and the Gust profile lists three employees, prototype-ready stage and LLC incorporation in Paris.
Risks & controversies
No controversies are reported in the sources. Notable data risks for the profile: public sources disagree on founding year (EU-Startups states 2020), funding is unannounced, headcount is very small (three), the Gust listing describes the company as only prototype ready, and the team member named in public listings (Edoardo Barp on Gust) differs from the leadership recorded internally.
