depthfirst

depthfirst is a unified code-to-production security platform. It combines deep understanding of applications and systems with autonomous agents to continuously discover, fix, and prevent security issues, delivering always-on defense. The platform covers three broad areas: - Code Security reviews repositories and pull requests for vulnerabilities, secrets, insecure dependencies, and business-logic flaws. It connects findings to application context so security and engineering teams can focus on the issues that matter and fix them in the code. - Agentic Pentesting uses autonomous agents to attack running applications like a team of elite security researchers. It supports black-, gray-, and white-box testing for new vulnerability discovery, but can also confirm whether code scan findings are exploitable and replay attacks to verify that fixes work. - Dependency Firewall blocks malicious packages before installation to prevent supply chain attacks. It applies a shared security policy at the artifact-repository layer and on managed devices, protecting both people and AI agents. Beyond identifying issues, depthfirst generates fixes and opens pull requests for the engineers responsible for the code, connecting detection, validation, remediation, and retesting in one platform. depthfirst’s in-house research lab develops specialized cybersecurity models, including dfs-large1, and benchmarks AI systems on security tasks. depthfirst works with enterprises such as ServiceNow, government agencies, and innovative AI and fintech companies including Lovable, Supabase, Ripple, Listen Labs, fal, and MoonPay.

How it works

Gordon VAPT

Gordon Vulnerability Assessment and Penetration Testing (VAPT) combines automated vulnerability scanning with certified analyst-led penetration testing in a single, continuously available service, eliminating the gap between scheduled assessments and ongoing exposure. The service begins with automated discovery and vulnerability scanning across an organization's external and internal attack surfaces, including network infrastructure, web applications, APIs, cloud environments, and endpoints. Discovered vulnerabilities are validated to remove false positives before results are presented, so every finding in the report reflects a confirmed, exploitable issue rather than a raw scanner output. Certified penetration testers then conduct manual exploitation testing against scoped targets, simulating the tactics, techniques, and procedures used in real-world attacks, including privilege escalation, lateral movement, authentication bypass, injection flaws, and business logic vulnerabilities that automated tools cannot detect. Testing covers external network, internal network, web application, API, and cloud infrastructure scopes, configurable per engagement. Each assessment produces two report formats from the same findings: a technical report with full exploit chains, affected assets, CVSS scores, and step-by-step remediation guidance for security and engineering teams; and an executive summary in plain language for leadership and compliance stakeholders, with a risk rating, business impact statement, and remediation priority order. Both are delivered within the agreed SLA, without requiring the customer to reformat or translate findings. Completed assessments map findings to the requirements of SOC 2, ISO 27001, PCI DSS, HIPAA, NIST CSF, and Cyber Essentials. Customers receive a remediation verification retest at no additional cost to confirm fixes before closing the engagement. All scoping, scheduling, reporting, and retest requests are managed through a self-serve portal, with no email-based coordination.
