Cosmos is Bishop Fox's cloud-native technology platform and the foundation of its offensive security services. Cosmos is built on stateless microservices that auto scale to enterprise volumes, continuously discovers external assets, and routes high-confidence findings into an expert human validation pipeline. Cosmos builds and verifies a living inventory of an organization's external attack surface. Cosmos runs daily automations that validate reachability and protocol behavior so customers see only verified, visible assets. Cosmos captures evidence in the form of technology fingerprints, screenshots, and service metadata. Cosmos uses tenant- and organization-level cloud connectors. Cosmos integrates with customer workflows through Jira and ServiceNow, syncing validated findings into existing ticketing systems. Validated outputs are surfaced through the Bishop Fox Portal, which provides an asset inventory, confirmed findings, indicators of exposure, and a triage workflow integrated with customer ticketing and collaboration systems. Bishop Fox operates and manages Cosmos as part of its services, and customers do not deploy or maintain the platform themselves.^[7]

Bishop Fox built AIMap, an open-source tool that discovers, scores, and tests exposed AI endpoints. Sliver is a cross-platform general purpose implant framework. Sliver supports asymmetrically encrypted C2 over DNS, HTTP, HTTPS, and Mutual TLS.

Bishop Fox says it helps customers who are looking to safely deploy AI, release a new app or service, or validate corporate governance. A healthcare technology company moving to SaaS needed to validate its multi-tenant cloud platform, secure connected device provisioning, and maintain visibility across a growing attack surface. An energy provider faces constant threats from nation-state actors targeting critical infrastructure. Equifax runs year-round perimeter testing to safeguard high-value data. Zoom used continuous attack surface monitoring to protect its expanding platform.

About BreachLock

BreachLock sells human-delivered, AI-powered and automated testing for attack surface management, penetration testing as a service, and automated pentesting and red teaming, integrated into the BreachLock Platform. BreachLock pairs Breach360 autonomous pentesting with CREST-certified, expert-led testing on demand, available from a single platform. On the unified platform, ASM discovers what is exposed, Breach360 proves what is exploitable and how, and PTaaS brings in certified pentesters when compliance or complexity demand it.^[1][3][4][5]

Breach360 continuously tests a web and network attack surface and proves every confirmed finding with a working exploit. Breach360 is trained on 40K+ real-world penetration tests. Breach360 executes complex, multi-step attack scenarios from reconnaissance to kill chain execution, moving laterally and pivoting between systems. Breach360 executes the entire attack, from reconnaissance to enumeration, exploitation and lateral movement, with live screenshots of every step. Customers can target Breach360 by IP, domain, hostname, app or API, and choose threat groups to mirror, attack intensity, and TTPs.^[4][5]

For web applications, Breach360 drives a real browser and uses multimodal reasoning to chain exploits across authentication and complex workflows. Breach360 drives a real browser through logins, multi-step flows, and the business logic behind them, supplying credentials and MFA where needed. Breach360 generates PDF reports directly in the platform for executive and technical audiences.^[6]

BreachLock PTaaS combines certified, expert-led penetration testing with agentic AI-powered acceleration. BreachLock's certified in-house pentesters test across web applications, APIs, networks, cloud environments, mobile apps, LLMs, and more. Every BreachLock pentest is conducted by in-house certified pentesters across the U.S., Europe, and Asia carrying certifications including CREST, OSCP, OSCE. BreachLock's autonomous penetration testing engine handles host discovery, port scanning, service and protocol enumeration, and initial vulnerability scanning and exploitation. Every finding that Breach360 surfaces is validated by a certified pentester. Every finding across ASM, Breach360, and PTaaS includes evidence, remediation guidance, and business context. The BreachLock Unified Platform generates compliance-ready, executive, or technical reports mapped to SOC 2, PCI DSS, ISO 27001, HIPAA, and HITRUST.^[1][5][7]

BreachLock ASM continuously scans and inventories internet-facing assets, including domains, subdomains, IPs, exposed services, shadow IT, and third-party infrastructure. Starting with a seed domain, ASM investigates DNS records, MX records, CNAMEs, and certificate data to identify associated subdomains, IP addresses, and exposed services, including shadow IT. ASM runs continuously on daily, weekly, or custom schedules. ASM correlates an organization against threat intelligence feeds and public breach data to identify exposed credentials. ASM is subscription-based with unlimited scanning across all asset types. ASM scores and prioritizes vulnerabilities using OSINT, CVSS, and known breach data. ASM findings feed directly into AEV for autonomous pentesting and PTaaS for certified penetration testing right in the BreachLock Unified Platform.^[5][7]

BreachLock's 100% in-house, certified pentesters test applications, networks, APIs, IoT devices, cloud assets, and LLMs. BreachLock application pentesting covers web, mobile, thick-client, and the APIs and code behind them. BreachLock tests external and internal networks, wireless networks, and segmentation controls. BreachLock cloud pentesting covers hybrid and multi-cloud infrastructure, AWS, Azure, and GCP environments, containers, Kubernetes, and the control plane. BreachLock pentesting also covers AI and large language model applications, testing for prompt injection, data leakage, and integration risks unique to LLM deployments.^[9]

BreachLock RTaaS combines human-delivered red teaming with modern technologies. The BreachLock Red Team as a Service (RTaaS) model tests the defense of an entire security ecosystem to assess and validate exposures against a mature security offense. BreachLock's red team tests a security team's readiness to defend against an actual cyber-attack by attempting to exploit security weaknesses just as real attackers would.^[1][10]

BreachLock has been conducting continuous security testing for over five years and has performed thousands of penetration tests. BreachLock uses automated algorithms and supervised NLP-based AI models to refine its proprietary Pen Testing framework. BreachLock's framework automates routine tasks like report formatting, proof of concept integration, and consistency in vulnerability identification.^{[1][2][3][4][6][7][11]}
