How an organisation's domains are configured to resist impersonation and unauthorised sending, and whether those controls are applied consistently across the estate.

Digital Trust Intelligence
Soterius helps organisations understand externally observable digital trust and security signals across their internet-facing estate — the same signals that customers, partners and regulators can see.
We work from the outside in, using evidence an organisation already publishes to the internet, and turn it into a picture leaders can act on.
What we do
We evaluate what an organisation shows the world
Every organisation leaves a public technical footprint: the domains it owns, the services it runs and the way those are configured. Soterius evaluates the externally observable signals within that footprint which can affect digital trust and operational risk.
The result is a consistent, comparable view of how an organisation presents itself online — across a single business or an entire group.
Domain and DNS controls
How domains and their supporting records are structured and maintained, and what that says about the way an organisation's online identity is governed.
Web and TLS configuration
How public web services and their transport security are presented to the outside world, and whether that presentation holds up across every service an organisation runs.
Externally observable security posture
The wider picture formed by everything an organisation publishes to the internet, assessed from the outside and interpreted in business terms.
Soterius works only from externally observable evidence. We do not require access to internal systems, networks or credentials, and we are not a penetration-testing service. Everything we report is derived from information an organisation already publishes to the internet.
Who we help
Wherever digital trust carries weight
Digital trust matters to any organisation whose customers, partners or public depend on it being who it says it is online. Soterius is built to serve that need broadly rather than for one narrow market.
Organisations
From single-domain businesses to groups operating many entities, brands and internet-facing estates.
Boards and risk teams
People accountable for digital risk who need a clear view of exposure without having to interpret raw technical output.
Technology and security leaders
Teams who need consistent, evidence-based visibility across the estate they are responsible for.
Regulated and public-interest sectors
Settings where digital trust, continuity and accountability matter to people beyond the organisation itself.
Why Soterius
Observed, explained, and revisited
Digital trust questions are usually answered with assertions. Soterius answers them with observation — recorded, explained and repeated as things change.
01
Evidence, not assumptions
Findings are grounded in observed configuration recorded at a point in time, rather than questionnaires or self-declaration.
02
Visibility across estates
Observation across many organisations, domains and services at once, so patterns are visible rather than isolated.
03
Understandable findings
Technical observations explained in language a board and an engineering team can both act on.
04
Ongoing change awareness
External configuration drifts over time. Repeat observation shows what has changed, what has been fixed and what has not.
