Sentrii — Threat Hunting AI

Threat Hunting AI — scan suspicious links, dApps, files, and repos before you touch them.

Sentrii — Threat Hunting AI AI-Powered Threat Scanner for the Web Sentrii is an intelligent threat investigation agent that scans suspicious links, files, code repositories, and Solana wallet interactions before you touch them. Stop wondering if that link, download, or dApp is safe — let AI hunt the threat for you. Requires a free Sentrii account. New users receive 20 free credits on signup — enough to run normal scans and a deep browser scan. To get started, install the extension, click the Sentrii icon, and sign in. Why install Sentrii? The web is full of traps. Phishing links, malicious downloads, compromised GitHub repos, and wallet drainers are everywhere. Sentrii sits in your browser toolbar, ready to investigate anything suspicious with one click. It combines real-time threat intelligence, sandboxed browsing, static malware analysis, supply-chain auditing, and blockchain state checks into a single streamlined workflow — powered by AI that explains every verdict in plain language. Scan anything, instantly: Website Scanner — Paste any URL and choose your depth. Normal mode (2 credits) checks threat intel databases, DNS reputation, and SSL config. Deep mode (10 credits) opens the page in an isolated browser — no risk to your machine — and watches for phishing, credential harvesting, redirect chains, and malicious scripts. Wallet Interaction mode (15 credits) adds simulated Solana transaction preflight to catch drain contracts before you sign. File Malware Scanner — Upload any file up to 32MB. Sentrii fingerprints the file (SHA-256), checks 70+ antivirus engines via VirusTotal, and optionally submits to sandbox analysis (Hybrid Analysis / ANY.RUN). Results include threat classification, behavior summary, and a trust score. Repository Supply-Chain Scanner - Paste a GitHub repo URL. Sentrii extracts dependency manifests (package.json, requirements.txt, go.mod, Cargo.toml, etc.), cross-references every package against OpenSSF's malicious packages dataset, flags typosquatted dependencies, and checks for suspicious npm scripts, preinstall hooks, and embedded credentials. Wallet Exposure Scanner — Enter a Solana wallet address. Sentrii inspects token accounts for risky delegations, identifies suspicious token approvals, checks for NFT drainer patterns, and surfaces addresses flagged in blockchain threat feeds. Know if a wallet has been compromised before you send funds. Who is Sentrii for? - Crypto users — Check dApps, wallets, and transactions before connecting your wallet or signing. Avoid phishing sites, malicious airdrops, and drain contracts. - Developers — Audit dependency trees in open-source repos. Catch typosquatted packages, compromised maintainers, and supply-chain attacks before they reach your build. - Security researchers — Investigate URLs and files at scale. Sentrii's multi-stage pipeline gives you reputation checks, sandbox behavior, and AI analysis in one place. - Everyone else — Got a weird link in a Telegram message? Suspicious email attachment? Unknown file from a recruiter? Scan it before you open it. How it works: 1. Click the Sentrii icon in your browser toolbar 2. Paste a URL, select a file, or enter a wallet address 3. Choose your scan depth and hit scan 4. Watch the pipeline stages in real time — reputation check, deep browser, AI judge, and verdict 5. Read the plain-English receipt with threat breakdown, severity score, and specific recommendations What makes Sentrii different: - Multi-engine approach — No single source of truth. Sentrii aggregates threat intel, sandbox behavior, AI reasoning, and blockchain state into one unified verdict. - AI-powered analysis — Every scan includes an AI judge that reviews all evidence and writes a human-readable threat assessment. No confusing raw data dumps. - Isolated browser — Deep scans open pages in a sandboxed Playwright browser. If the page is malicious, your machine never touches it. - Download auto-detection — Sentrii will automatically detect when you download a scannable file and offer to scan it before you open it. - Credit-based, no subscription — Buy credits as you need them. 1 credit ≈ $0.20. Normal URL scans start at 2 credits. No monthly commitment. Privacy: Sentrii only sends data you explicitly choose to scan — URLs, file hashes, repo URLs, and wallet addresses. When you scan a URL, Sentrii also captures a screenshot and visible page text from your current tab to help the AI analyze the page. No browsing history, form data, keystrokes, or personal data is ever collected or transmitted. Ready to hunt threats? Install Sentrii and scan your first link in seconds. Your browser, your data, your safety — with an AI investigator on your side.
