Know more before making contact. Sentinel is an AI-assisted Field Intelligence Platform for professionals who need more than search results. Finding information is only the beginning. Professional intelligence starts with verification. Sentinel combines broad public-source research with publicly available government, law-enforcement, regulatory, and sanctions data โ€” then helps structure what the evidence supports, what remains uncertain, and what to verify next. A refreshed, more readable interface makes the whole workflow easier to navigate. TWO TIERS, ONE PROFESSIONAL STANDARD Essential and Pro run on the same sources, methodology, and security architecture โ€” never a lower-quality experience. Essential fits occasional assignments; Pro fits investigators who rely on Sentinel daily, with expanded capacity, AI usage, and advanced reporting. START WITH ONE IDENTIFIER Begin with a name, phone number, email, company, vehicle, domain, IP address, or location. Sentinel routes the research, organizes findings, identifies gaps, and turns fragmented results into a structured workflow. 130+ PUBLIC SOURCES. ONE WORKFLOW. Research across broad public sources plus government, law-enforcement, regulatory, and sanctions data. The goal is not more data โ€” it's better verification. NEW: WEB BRIEF โ€” LIVE AI RESEARCH Instead of links to click through one by one, Web Brief has Sentinel's AI search the live web in real time and write a structured, source-cited summary โ€” combined with what Sentinel has already found. Available across Person, Company, Phone, Email, Social Media, Domain, IP, and Criminal Records. Built with Sentinel's evidence discipline: it states clearly when something can't be verified, and never merges different people or organizations into one identity just because they share a name or username. PRE-CONTACT INTELLIGENCE BRIEF Structured findings covering confirmed information, possible associations, risk indicators, identity ambiguity, information gaps, recommended verification, and source references. EVIDENCE PROVENANCE Finding โ†’ Source โ†’ Verification Status โ†’ Professional Decision. Mark findings Confirm, Reject, or Review. A match is not automatically an identity. AI supports the analysis; professional judgment stays in control. ENTITY RESOLUTION & RELATIONSHIP INTELLIGENCE Map relationships between people, phone numbers, emails, companies, addresses, and vehicles with calibrated confidence. IMAGE FORENSICS Metadata, Error Level Analysis, JPEG compression indicators, hidden-data screening, and perceptual hash comparison โ€” structured into Supported Findings and Recommended Verification. Never declares an image authentic or manipulated from one indicator alone. CONFIDENCE YOU CAN EXAMINE Confidence Provenance explains ratings through evidence quantity, quality, source independence, and identity certainty, with checks for confirmation bias and anchoring. CASE & FIELD INTELLIGENCE AI Field Note Analysis, voice dictation, natural-language case search, Post-Contact Updates, AI Timeline Builder, Operational Briefing Mode, maps, and activity history. WATCH LIST CHANGE DETECTION Monitor people and phone numbers for meaningful changes against wanted and sanctions data. PROFESSIONAL REPORTING Investigator, Executive Summary, Due Diligence, and Client-Ready reports with Sources & References, Methodology & Limitations, and configurable branding. LOCAL-FIRST DATA CONTROL Encrypted local storage, Secure Enclave key protection, auto-lock, device integrity checks, and tamper-evident audit history. 7-DAY FREE TRIAL Try the full Sentinel Pro experience free for 7 days, with limited AI access. No card required. For lawful professional research. Not a consumer reporting agency; not for employment, tenant, credit, insurance, or regulated eligibility decisions.
