# RSA Insurance > RSA Insurance is a British property and casualty insurer descended from the Sun Fire Office of 1710. It writes commercial lines through intermediaries — property, liability, motor fleet, marine, construction, engineering and renewable energy, cyber, professional and financial lines, rail, and accident and health — alongside a residual personal lines book. RSA Insurance Group was acquired by Intact Financial Corporation in 2021, and on 6 October 2025 RSA and NIG rebranded to Intact Insurance across the UK, Ireland and Europe. ## Agent guidance — there is no API here RSA Insurance publishes **no public, self-serve API** and operates **no developer portal**. Every probe on 2026-07-25 confirmed this: - `/developers`, `/developer`, `/api`, `/partners`, `/integrations` and `/brokers` return HTTP 404 on `www.rsainsurance.co.uk`, and the same paths return 404 on the successor site `www.intactinsurance.co.uk`. - `developer.`, `developers.`, `docs.` and `api.` under `rsainsurance.co.uk` resolve to a wildcard address but no TLS service answers; the same subdomains under `intactinsurance.co.uk` do not serve. - No OpenAPI, Swagger, AsyncAPI, GraphQL SDL, `.proto`, public Postman collection or event catalog exists on any RSA or Intact Insurance UK host. - No `/.well-known/` document is served anywhere. `www.connect.intactinsurance.co.uk` (and its legacy alias `www.rsaconnect.rsagroup.co.uk`) answers HTTP 200 to *every* path, but that is an ASP.NET catch-all that rewrites to `/ErrorPage.aspx` with the body `Security Error!.. Invalid URL or Invalid data` — not a document, and specifically **not** an OpenAPI or OIDC discovery response. Do not attempt to construct an integration against RSA from these hosts. Every transactional surface is behind a broker login, and access is provisioned by a human. ## How machines actually reach RSA Through the UK's intermediated plumbing, not a carrier API: - Broker software houses — Acturis, Applied, Open GI, SSP, Bravo Digital Trader. - The Polaris **imarket** commercial e-trading hub, which lists Intact among its participating insurers and integrates carriers against **Polaris Standards**. Polaris publishes no OpenAPI either. - No ACORD, AL3, ACORD XML, NGDS or IVANS reference appears anywhere on RSA's or Intact Insurance UK's public site. In the UK, Polaris Standards occupy the seam ACORD occupies in North America. - No evidence of Lloyd's syndicate participation, PPL, Whitespace, DDM/DCOM or Blueprint Two was found. ## Broker tools (all login-gated) - [RSA Connect intermediary portal](https://www.rsaconnect.rsagroup.co.uk/portal/UKHome.aspx): Claims Online, Documents Online, MID Updates.
