SILENTCHAIN Professional doesn't just flag vulnerabilities - it actively validates them to confirm they are real. AI-driven payloads, out-of-band callbacks, and 24-WAF fingerprinting turn a wall of maybes into a short list of proven findings you can hand a client with confidence. With a local model, no proxy traffic, findings, or credentials are sent to a third-party AI - it all stays on your hardware.

Advanced capabilities designed for penetration testers, red teamers, and bug bounty hunters.
Move beyond AI suggestions to verified findings. AI-guided testing generates targeted payloads from 200+ curated OWASP payloads, automatically fingerprints 24 WAF technologies, and performs out-of-band testing for XSS, SSRF, XXE, RFI, and blind injection to confirm suspected vulnerabilities with evidence.
Deploy SILENTCHAIN with a local Ollama model to keep analysis entirely on your own hardware. No requests, responses, or findings leave your environment when using local AI. Cloud providers remain optional, with sensitive data sanitized before external AI requests.
Works natively inside Burp Suite Professional. SILENTCHAIN adds a dedicated scanning console, integrates findings into Burp's native Issues panel, and exports evidence-rich reports without changing the workflow you already use.
Choose from 10 AI providers, including Burp AI, Ollama, OpenAI, Claude, Claude Code, Gemini, OpenRouter, GPT-5.5, Z.ai, and Azure AI Foundry. Use local models for self-hosted analysis or connect to cloud providers for additional reasoning capabilities.
Generate professional HTML advisory reports with verified findings, evidence, request/response pairs, severity scoring, and remediation guidance. Findings are clearly separated between AI-suspected and actively verified issues for transparent reporting.
Every finding is automatically mapped to the OWASP Top 10 and a CWE identifier with severity scoring. Reports align with industry-standard frameworks, making it easier to prioritize remediation, communicate risk, and integrate findings into existing security workflows.
Watch how SILENTCHAIN AI detects and actively verifies vulnerabilities in real time inside Burp Suite.
A native Burp workflow: a scanning console inside Burp, findings in Burp's own Issues panel, and reports you can hand directly to clients.
SILENTCHAIN adds its own tab to Burp Suite Professional with live statistics, queued and completed analysis tasks, a sortable findings table, and a streaming console for monitoring analysis in real time.
In this assessment, SILENTCHAIN observed 4,908 requests and created 117 findings, including 56 High severity issues. Duplicate and rate-limit skips are tracked separately, showing where analysis effort and target load are being spent.
Every finding registers as a native Burp issue with a full advisory, request and response details, evidence, CWE mapping, and remediation guidance - so it flows directly into the Burp workflow and exports you already use.
Verified issues carry a VERIFIED tag. Findings from AI analysis alone are clearly labeled with their confidence level instead of being presented as confirmed vulnerabilities.
Export a self-contained HTML advisory report with severity breakdowns, top findings, and verified counts that clearly separate confirmed issues from AI-suspected findings.
In this assessment, 35 of 117 findings were confirmed by Phase 2 payload delivery - and the report shows exactly which findings were verified, so nobody has to take the number on trust.

Data residencySILENTCHAIN is an AI-powered Burp Suite Professional extension that helps security professionals discover, validate, and report web vulnerabilities. It analyzes traffic flowing through Burp and uses AI-assisted detection to identify potential issues. Professional adds active verification to confirm findings with evidence.
SILENTCHAIN supports multiple AI providers, including local models through Ollama, so teams can choose between cloud-based AI capabilities or private, self-hosted analysis.
Yes. SILENTCHAIN requires Burp Suite Professional and does not run on Burp Suite Community.
Burp Suite Professional is a separate product from PortSwigger and is not included with SILENTCHAIN. You provide your own Burp Suite Professional license.
Community provides AI-assisted OWASP Top 10 detection, multiple AI providers, sensitive-data sanitization, and Burp Suite integration so you can try SILENTCHAIN with your own authorized testing.
Professional adds active verification, WAF detection and fingerprinting, out-of-band testing, additional AI providers, offensive AI models, and advanced reporting features.
Start with Community and upgrade to Professional when you need verified findings and deeper testing capabilities.
After checkout, your SILENTCHAIN Professional license key is emailed to your order address. Paste the key into the SILENTCHAIN License dialog inside Burp to activate your installation.
Checkout is secure and handled through the SILENTCHAIN store.
Yes. Your Professional license is transferable between machines. Deactivate it on one machine and activate it on another. A license can be active on one machine at a time.
No. SILENTCHAIN Professional is an annual license and does not silently auto-renew. We will notify you before your license expires so you can decide whether to renew.
Yes, with a local AI model. Connect SILENTCHAIN to Ollama and run AI analysis entirely on your own hardware. Requests, responses, and findings are not sent to a third-party AI provider.
Cloud AI providers are optional. When using external providers, sensitive data is sanitized before requests are sent.
Not when using a local AI deployment. With Ollama or another self-hosted model, requests, responses, and findings remain on your hardware.
Cloud AI providers are optional, and SILENTCHAIN sanitizes sensitive data before external AI requests.
SILENTCHAIN supports 10 AI providers, including Burp AI, Ollama, OpenAI, Claude, Gemini, OpenRouter, Z.ai, GPT-5.5, Claude Code, and Azure AI Foundry.
Burp AI uses your existing PortSwigger AI credits. Ollama uses local models with no API cost. Other cloud providers may require your own API credentials.
SILENTCHAIN Professional itself is unmetered - there are no per-request AI charges from SILENTCHAIN.
Yes. SILENTCHAIN is an offensive security testing tool intended for authorized use only. Use it only against systems you own or have explicit permission to test.
Because SILENTCHAIN Professional is a digitally delivered software license, license purchases are non-refundable once issued.
To make evaluation easy, the free Community edition lets you test the SILENTCHAIN workflow against your own authorized targets before upgrading. You can also review the Professional demo and documentation before purchasing.
Upgrade to Professional when you are ready for active verification, WAF-aware testing, advanced reporting, and additional AI providers.
No. SILENTCHAIN is a Burp Suite Professional extension and works inside the Burp workflow you already use. It does not include Burp Suite, replace Burp Suite Professional, or integrate with the Sn1per platform.
