What it sells: Cobalt

What Autonomous Pentest does[3][7]
Cobalt Autonomous Pentest is overseen by Cobalt Core pentesters. Cobalt says it delivers complete pentests in 24 hours with proof of exploit on every finding.

What Secure Code Review does[8]
Secure code review is described as human-led analysis of source code. Cobalt uses SAST and SCA for automated scanning and then manually reviews the output to validate findings.
What Internal Network Pentest does[10]
Cobalt says its experts use network scanning tools, exploit frameworks and manual techniques to find and exploit vulnerabilities in internal systems. Findings appear in real time on the Cobalt platform with remediation guidance.

What it sells: Fleuret AI

What Émile does[4][6]
A separate validator confirms every finding with a non-destructive exploit. Every finding ships with a working, replayable exploit. Each finding lands as a ticket with its exploit, an owner and a remediation, pushed to Jira, Linear or Slack.
What Hortense does[4][5][6]
Hortense maps a customer's estate from domain to database. Hortense crosses what changed in the code with what is exposed on the internet and what past pentests found. Hortense prepares the scope, and a person with launch rights starts the pentest, which Émile runs. Hortense comes with every yearly plan.

About Cobalt

Cobalt offers a full suite of offensive security services, from autonomous pentesting to human-led pentesting. The Cobalt Offensive Security Platform helps customers move beyond point in time pentesting to a continuous offensive security program.[1][3]

Cobalt says most pentesting programs still operate on an annual cycle. Cobalt describes the gap between how fast risk changes and how often organizations test for it as the exposure adversaries count on.[7]

The Cobalt Platform centralizes access to the full range of security testing services: web app, API, cloud, network, red teaming, AI and LLM, and more. Customers can launch a pentest in hours and get real-time findings. Customers can collaborate directly with testers via the platform, Microsoft Teams or Slack. Cobalt says Cobalt Sage AI powers every Cobalt pentest and is built on 13 years of expertise, informed by thousands of security engagements. Cobalt says Cobalt Sage AI removes the reconnaissance, scanning, triage and reporting work so human experts can focus on complex attack paths and creative scenarios.[1][3][4][7][10]

Cobalt delivers penetration testing across the entire application portfolio to find and fix vulnerabilities before they are exploited. Cobalt says network and cloud infrastructure are high-value targets in a constant state of change, and that Cobalt identifies and validates real exposures across the attack surface. Network and cloud testing covers Internal Network Pentest, External Network Pentest, Cloud Pentest and Cloud Configuration Review. Advanced offensive security services from Cobalt test systems against the tactics and techniques of a sophisticated adversary. Cobalt's advanced services include Red Teaming, Digital Risk Assessment and Secure Code Review. Customers use Cobalt to test critical web applications and APIs in production, AI and LLM-based applications still in development, and globally distributed networks segmented by location and business unit. For code review, Cobalt uses SAST and SCA for automated scanning and then reviews the scanner output manually to validate the findings.[3][4][8][10]

Cobalt offers two testing delivery models. Customers can choose one or mix and match depending on assets, environment, release cycles and goals. Human-led testing draws on purpose-built methodologies and 500+ vetted security experts in the Cobalt Core. Cobalt Autonomous Pentest delivers complete pentests in 24 hours with proof of exploit on every finding, overseen by Cobalt Core pentesters. Agentic Penetration Testing as a Service pairs AI-driven automation with human pentesters to deliver continuous offensive security. Cobalt says periodic penetration testing meets compliance deadlines and continuous testing gives coverage in between.[3][4][7]

Cobalt pushes vulnerability data into Jira, GitHub, ServiceNow and more through 50+ integrations. Cobalt offers unlimited retesting with a seven-day SLA. Cobalt offers centralized management of parent and child organizations. Cobalt says its customizable reports are mapped to SOC 2, ISO 27001, HIPAA and PCI-DSS. A Cobalt Credit represents the equivalent of 8 hours of offensive security testing. Cobalt sells credits in annual packages that include asset scoping, testing, retesting and platform access. Credits do not roll over into the next contract.[2][3][4][7][9]
