Introduction:
The cybersecurity industry has long been caught in an impossible trade-off: depth or breadth. Critical crown-jewel assets sit exposed for months between infrequent manual penetration tests, while automated vulnerability scanners drown security teams in theoretical noise without confirming what is actually exploitable. Meanwhile, attackers have already turned to AI to probe continuously, leaving defenders who rely on point-in-time snapshots dangerously behind. Bugcrowd’s launch of Savant Pathseeker—the first solution in its new Agentic Offensive Testing portfolio—marks a fundamental shift in how security teams approach external attack surface testing, delivering continuous, evidence-based agentic penetration testing across every external web application and API.
Learning Objectives:
- Understand the architectural and operational differences between traditional vulnerability scanners and agentic penetration testing systems
- Learn how to implement continuous, scope-controlled offensive testing across web applications and APIs
- Master the integration of autonomous agentic findings with human-led validation workflows for complex vulnerabilities
You Should Know:
- Beyond the Scanner: What Makes Agentic Pentesting Different
Traditional vulnerability scanners run predefined checks and flag theoretical issues, leaving security teams to determine whether those findings can actually be used in an attack. Savant Pathseeker is fundamentally different. As Braden Russell, Bugcrowd’s Chief Product Officer, explains: “Pathseeker is not a scanner with an AI layer bolted on. Scanners run pre-defined checks and flag theoretical issues. Pathseeker uses purpose-built agentic systems that plan, probe, and attempt actual exploitation across web applications and APIs, delivering evidence-based findings with reproducible proof of exploitability, not just a list of potential flaws”.
The system employs a proprietary layer of security testing skills and orchestration built on third-party AI models, developed by Bugcrowd’s own offensive security practitioners. These capabilities include autonomous API fuzzing, application testing, and attack-path reasoning. Critically, Bugcrowd does not use customer or researcher data to train or tune the models powering Savant Pathseeker—a vital assurance for regulated industries.
Step-by-Step: Understanding the Agentic Testing Workflow
- Scope Definition: Security teams define which external web applications and APIs are approved for testing, establishing operational guardrails and parameters.
- Continuous Reconnaissance: Purpose-built agents perform ongoing reconnaissance, mapping the attack surface and identifying potential entry points.
- Autonomous Probing and Exploitation: Agents plan, probe, and attempt actual exploitation across approved assets, handling common and moderately complex issues.
- Validation and Evidence Generation: Each finding is autonomously validated, with reproducible proof of exploitability attached—not just a severity score or theoretical risk rating.
- Unified Platform Delivery: Findings feed directly into Bugcrowd’s platform, correlated and prioritized alongside human results without tool-switching.
- Human Escalation: Complex business logic flaws, exploit chains, zero-day vulnerabilities, and high-impact attack paths can be escalated on-demand to Bugcrowd’s global community of human pentesters.
- Audit-Ready Reporting: The system generates audit-ready reports for security, compliance, and risk teams.

Practical Implementation: Commands and Tools for Agentic-Style Testing
While Savant Pathseeker automates the agentic testing process, security professionals should understand the underlying technical capabilities. Below are essential commands and tools that mirror the reconnaissance, fuzzing, and exploitation functions performed by agentic systems.
Linux Reconnaissance and API Discovery:
Install Arjun for API parameter discovery sudo apt install arjun Extract parameters from JavaScript files arjun -u https://target.com/api/endpoint -m GET Comprehensive subdomain enumeration amass enum -d target.com API endpoint discovery with ffuf ffuf -u https://target.com/FUZZ -w /usr/share/wordlists/api-endpoints.txt
API Fuzzing and Security Testing:
Install Wapiti for web application scanning sudo apt install wapiti Scan API endpoints with authentication wapiti -u https://api.target.com -a "Bearer <token>" -m all Burp Suite CLI alternative for lightweight testing pip install burpy burpy scan https://api.target.com/v1/users
Windows Active Directory Enumeration (for hybrid environments):

Exploitation Validation Commands:
Test for SQL injection with sqlmap sqlmap -u "https://target.com/api?id=1" --batch --level=2 Test for command injection curl -X POST https://target.com/api/execute -d "cmd=127.0.0.1; whoami" API authentication bypass testing curl -X GET https://target.com/api/admin -H "X-Original-URL: /admin"
3. Integrating Agentic Testing with Existing Security Programs
Savant Pathseeker does not operate in isolation. It integrates seamlessly with Bugcrowd’s full suite of offensive security offerings, including Penetration Testing as a Service (PTaaS), Bug Bounty programs, Vulnerability Disclosure Programs (VDP), Red Team as a Service (RTaaS), and attack surface monitoring. This integration allows findings uncovered through continuous agentic testing to move directly into deeper human-led investigation without being transferred to another system.
Step-by-Step: Integration Workflow
- Agentic Discovery: Pathseeker agents continuously identify and validate exploitable vulnerabilities across the external attack surface.
- Automated Triage: Findings are autonomously validated and delivered through the unified platform, sorting through noise and replacing disconnected workflows.
- Risk Prioritization: Findings are correlated and prioritized by exploitability, not just severity scoring.
- Human Escalation: For complex issues requiring adversarial creativity—business logic flaws, zero-days, exploit chains—teams can escalate directly to Bugcrowd’s researcher community.
- Remediation Tracking: The platform provides end-to-end visibility from discovery through remediation validation.
4. Scope Control and Operational Safety
One of the critical concerns with autonomous testing is maintaining strict scope boundaries. Savant Pathseeker addresses this with built-in guardrails and a manual kill switch that ensures testing stays within customer-defined parameters at all times. This is not optional—it is foundational to the product’s design.
Step-by-Step: Configuring Scope Controls
- Define Approved Assets: Specify which external web applications and APIs are in scope for continuous testing.
- Set Operational Guardrails: Configure testing parameters, including rate limiting, exclusion rules, and timing restrictions.
- Implement Kill Switch: Designate personnel authorized to manually stop all agentic testing activity immediately if needed.
- Monitor Activity: Continuously review testing activity through the platform dashboard.
- Audit Trail: Maintain comprehensive logs of all testing activities for compliance and audit purposes.

The Human-AI Symbiosis: Where Agents End and Experts Begin
Savant Pathseeker is explicitly designed to complement, not replace, human penetration testers. The agents handle reconnaissance, vulnerability mapping, exploitation attempts, and autonomous validation of common and moderately complex issues—providing broad, continuous baseline coverage across the entire external attack surface at a scale that human teams alone cannot match.
Human researchers remain essential for work requiring genuine adversarial creativity: complex business logic flaws, new exploit chains, zero-day vulnerabilities, and high-impact attack paths inside dynamic applications. As Russell explains: “Customers can escalate on demand through the same platform, the agents surface what is reachable, and the humans focus where depth matters most. The goal is not replacement. It is letting agents do what they do best and humans do what they do best, together”.
What Undercode Say:
- Agentic penetration testing represents a paradigm shift from point-in-time assessments to continuous, evidence-based security validation—closing the gap that attackers exploiting AI have already identified.
- The true differentiator will not be automation alone but how effectively vendors pair machine speed with human judgment, as Chris Steffen of Enterprise Management Associates noted.
The launch of Savant Pathseeker signals a broader industry movement toward continuous, AI-driven offensive security. Organizations that adopt agentic testing will gain a significant advantage: continuous visibility into exploitable risk, evidence-based prioritization, and the ability to scale security testing across every external asset without sacrificing depth where it matters most. However, this shift also demands new skills—security teams must learn to interpret agentic findings, manage autonomous testing workflows, and integrate continuous testing data into existing remediation processes.
For MSSPs and security service providers, Pathseeker offers a way to add continuous testing capabilities to their service portfolios, delivering greater value to clients while optimizing human resources for the most complex security challenges. The product is currently available through an early access program, with general availability planned for later this year.
Prediction:
- +1 Agentic penetration testing will become the industry standard within 24-36 months, rendering traditional periodic pentests obsolete for external attack surface validation.
- +1 Organizations that adopt agentic testing early will reduce their mean time to vulnerability remediation by 60-80% through continuous, evidence-based prioritization.
- -1 The proliferation of agentic testing tools will create a new class of “alert fatigue” as security teams struggle to triage validated findings at scale, necessitating AI-driven remediation automation.
- +1 Bugcrowd’s commitment to not using customer data for model training will set a privacy-first precedent that competitors will be forced to follow, particularly in regulated industries.
- -1 The gap between organizations that can afford agentic testing and those that cannot will widen, creating a two-tier security landscape where only well-resourced enterprises benefit from continuous autonomous protection.
- +1 The integration of agentic testing with bug bounty and VDP programs will create a virtuous cycle: agents find and validate common issues, while human researchers focus on the novel, high-impact vulnerabilities that drive true security innovation.
