Carrier SIU units
Extend your Special Investigations Unit with licensed field and open-source capacity when referral volume spikes or a claim needs boots on the ground.
SIU Support
SIU support for insurance fraud investigations.
SIU support is the investigative work behind an insurance carrier's Special Investigations Unit — developing the facts on a suspected fraudulent claim so it can be referred, denied, or defended. OnTrial adds licensed field and open-source capacity to your SIU, analyst-verified.
Workers' compensation, auto, property, and liability fraud. Fixed cost per engagement. Rush deployment available.
What it is
Turn fraud indicators into a documented record.
A red flag is a suspicion. An SIU investigation makes it a fact — or clears it.
A Special Investigations Unit is the team an insurer relies on to investigate claims that show signs of fraud. SIU support is the outside investigative capacity behind it — the licensed surveillance, background research, canvassing, and recorded statements that turn a red-flagged claim into a documented factual record the carrier can act on.
OnTrial runs SIU referrals intelligence-led: an open-source and background workup scopes the claim before operators deploy for sub rosa surveillance or field canvassing. See the glossary for the terms of art — SIU, EUO, sub rosa, AOE/COE.

Develop the indicators behind a suspicious claim — inconsistencies, prior-claim history, and relationships — into a documented factual basis for referral or denial.
Sub rosa surveillance
Covert, lawful activity-check surveillance to test a claimant's stated restrictions against their real-world activity, captured as timestamped video.
Background & social-media workups
Identity, prior claims, litigation history, and adverse-media research, plus DeepMedia social-media capture across 400+ platforms with archive preservation.
Canvassing & recorded statements
Neighborhood and scene canvassing, witness location, and structured recorded statements that preserve testimony for EUO, denial, or trial.

FAQ
SIU support, explained.
- What is SIU support?
- SIU support is the investigative work that backs an insurance carrier's Special Investigations Unit (SIU) — the team responsible for investigating suspected fraudulent claims. It develops the facts behind a red-flagged claim, through surveillance, background research, canvassing, and recorded statements, so the SIU can refer, deny, or defend the claim on a documented record. Carriers use outside investigators like OnTrial to add licensed field and open-source capacity to their SIU.
- What does an SIU investigation include?
- It combines red-flag and referral investigation, sub rosa surveillance, background and social-media workups, neighborhood and scene canvassing, and structured recorded statements. On a workers' compensation claim it is frequently paired with an AOE/COE investigation. Every finding is analyst-verified and documented for evidentiary use.
- When should a carrier refer a claim to an outside SIU investigator?
- When a claim shows fraud indicators the internal team can't resolve from the file alone — inconsistent statements, a suspicious loss pattern, prior-claim history, or social-media signals — or when the matter needs licensed surveillance or field canvassing. Referring early preserves witness memory and documents activity before an IME, EUO, or reserve decision.
- Can OnTrial support an examination under oath (EUO)?
- Yes. Pre-EUO subject workups — background, social media, geolocation, and field corroboration as warranted — are a routine part of SIU support, giving counsel a documented factual basis going into the examination.
- How fast is turnaround on an SIU referral?
- Activity-check surveillance returns in 1–5 business days standard; background and social-media workups follow the same model, with rush deployment available when a decision or examination is imminent. Every engagement is a fixed cost — no subscription or monthly fees.
