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 international sanctions data — then helps structure what the evidence supports, what remains uncertain, and what to verify next.
TWO TIERS, ONE PROFESSIONAL STANDARD
Essential and Pro run on the same sources, methodology, and security architecture — 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. Automated wanted and sanctions screening against FBI, Interpol, OFAC, UN, EU, BIS, and Canadian lists, plus broad public-source research. A check that cannot run is clearly marked as unavailable — never shown as a clean result.
FIELD BRIEF & FULL ANALYSIS
A Field Brief in seconds: wanted and sanctions results, risk flags, identity confidence, and the top checks before contact. Full Analysis adds associations, contradictions, information gaps, and source references.
WEB BRIEF — LIVE AI RESEARCH
Web Brief has Sentinel's AI search the live web in real time and write a structured, source-cited summary — combined with what Sentinel has already found. Available across Person, Company, Phone, Email, Social Media, Domain, IP, and Criminal Records. 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.
EVIDENCE PROVENANCE
Finding → Source → Verification Status → 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, vehicles, and domains with calibrated confidence.
IMAGE FORENSICS
Metadata, Error Level Analysis, JPEG compression indicators, hidden-data screening, and perceptual hash comparison — structured into Supported Findings and Recommended Verification. Never declares an image authentic or manipulated from a single indicator.
CASE & FIELD INTELLIGENCE
AI Field Note Analysis, voice dictation, natural-language case search, Post-Contact Updates, AI Timeline Builder, Operational Briefing Mode, maps, tasks, and activity history. Saved Field Briefs reopen from recent searches.
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. No tracking and no search logs.
7-DAY FREE TRIAL
