Security Assessment & Authorization Platform · Plain-language overview

Every assessment in one place.
Less admin, higher assurance.

Aegis SA replaces the email threads, spreadsheets, and scattered file shares behind security assessment & authorization with a single, AI-assisted platform — where assessors and project teams collaborate in real time, evidence lives in one auditable record, and every completed assessment becomes reusable knowledge for the next one.

The idea in one minute

What is Aegis SA?

Aegis SA is a security assessment & authorization platform — the single system of record for taking a system from intake, through control tailoring and evidence, to a signed Authority to Operate (ATO or iATO).

Getting a system authorized to operate is one of the most paperwork-heavy processes in IT security. Today it is run out of inboxes and workbooks: an assessor emails a control spreadsheet, a project team fills cells and attaches screenshots, versions fork, context is lost, and the “package” is really a folder of documents nobody can query. It is slow, error-prone, and impossible to reuse.

Aegis SA replaces that with one structured, permissioned workspace. Assessors and project resources work on the same living assessment. Controls are tailored to the system’s real risk profile. Evidence is captured in place, reviewed, scored, and turned into a defensible authorization decision — and every assessment feeds a growing, searchable knowledge base you own.

The plain version: Instead of a spreadsheet mailed back and forth, you get a shared assessment record. The assessor tailors the controls, the project team supplies evidence right on the control, an AI assistant drafts the guidance and narratives, and the finished package — and everything in it — stays centralized, auditable, and reusable.
Why this matters

The admin burden today

A typical assessment today is coordinated almost entirely by hand. To move one system toward an ATO, an assessor and a project team routinely juggle:

  • Back-and-forth email threads to request evidence, chase clarifications, and pass revised files around — the real “status” living in whoever’s inbox is most current.
  • Excel control workbooks that are copied, renamed, and forked until no one is sure which version is authoritative.
  • No central database. Evidence, narratives, and decisions are scattered across attachments, shared drives, and PDF reports that can’t be searched or reused.
  • Manual, repetitive work — retyping the same control language, re-collecting the same enterprise evidence, rebuilding the same report for every system.
  • Lost institutional memory. When an assessment finishes, its knowledge is buried in a file share; the next project starts from a blank sheet instead of inheriting what’s already proven.

The result is predictable: assessments take longer than the engineering work they gate, mistakes slip through the cracks, and skilled assessors spend their time on coordination and copy-paste instead of judgment.

The same people and the same evidence — but one queryable record instead of a dozen forked files, so nothing is lost, duplicated, or out of date.
The lifecycle, end to end

How it works

Aegis SA models the full authorization lifecycle as one guided flow. Each step builds on the last, and everything stays attached to the system it describes.

Flow From intake to authorization
  1. Intake. A project submits (or an assessor drafts) a structured intake describing the system, its data classification, and its risk profile — the starting point for scoping.
  2. Project & scoping. The intake becomes a project with a security profile and framework baseline (ITSG-33, NIST, CIS and more), setting the control set.
  3. Assessment & tailoring. The assessor tailors controls to the system’s real context — marking applicability, priority, and inheritance — instead of assessing a generic checklist.
  4. Evidence gathering. The project team supplies evidence directly on each control: narratives, configurations, screenshots and documents, with threaded comments in place.
  5. Review & audit. The assessor reviews each control, records results, and tracks gaps as POA&M items — all in the same record.
  6. Authorization. A defensible ATO or iATO package is generated, signed, and dated — with expiry and conditions captured for continuous oversight.
  7. Reuse. The finished assessment enriches your knowledge base, so the next system can inherit proven enterprise controls instead of starting from zero.
One source of truth: intake, controls, evidence, comments, POA&M, documents, and the signed authorization all live on the same record — permissioned, timestamped, and exportable — not spread across mailboxes and drives.
Where the AI does the heavy lifting

An LLM woven through the process

Aegis SA embeds a large language model at exactly the points where assessors and teams lose the most time — turning blank pages and manual copy-paste into a fast first draft that a human reviews and approves. The AI accelerates the work; the assessor stays in control of the decision.

01Smart intakeReads an uploaded system description or SADD and pre-fills the intake — classification, PII, technologies, activities — for the assessor to confirm.
02Control tailoringSuggests which additional controls a system’s risk profile warrants, with tailoring notes — so scoping is thorough, not guesswork.
03Evidence guidanceWrites plain-language guidance telling the project team exactly which artifacts, exports, and screenshots to provide for each control.
04Narrative draftingDrafts the evidence narrative from the system’s context, so a control write-up starts at 80% instead of a blank field.
05Inheritance detectionRecognizes enterprise controls already proven in prior authorized assessments and proposes them for reuse. (planned)
06Audit & scoringGenerates a step-by-step audit plan for the system’s tech stack, then reviews submitted proof and scores it. (planned)
Human-in-the-loop by design: every AI output is a reviewable draft, not an automatic decision. Assessors edit and approve — keeping the rigour of a manual assessment while removing the drudgery.
Assessors and project teams, together

Collaboration that reduces mistakes

Because the assessment is a shared, permissioned record — not a file in transit — the two sides of an assessment finally work in the same place, at the same time, with a clear division of roles.

AssessorsTailor controls, set evidence expectations, review submissions, and issue authorization — with full visibility into progress at a glance.
Project resourcesSee exactly what’s being asked, respond on the control itself, and get feedback in context — no guessing what a spreadsheet column meant.

Assignment, invitations, threaded comments, and role-based access mean the right person is responsible for the right control, and every exchange is captured against the evidence it concerns. Fewer handoffs means fewer dropped threads, fewer version mix-ups, and fewer mistakes reaching the authorization decision.

The shift: from “who has the latest file?” to “here is the current state of every control, and who owns it.” Coordination stops being a job in itself.
Every assessment makes the next one faster

Your own compounding knowledge base

The most expensive part of assessments is that they don’t accumulate. Each one is a fresh spreadsheet, and hard-won enterprise evidence — how identity, logging, or encryption is handled across the organization — gets re-collected from scratch every time.

Because Aegis SA keeps every assessment in one structured, queryable store, your organization’s history becomes an asset. Enterprise controls proven once — say, access control implemented through your identity provider — can be inherited into the next system, with the shared evidence referenced and only the system-specific details added on top. Controls are tailored from precedent, not reinvented.

  • Centralized, not sprawled — no more hunting through file shares and old email for how a control was handled last time.
  • Queryable — find every system that inherited a given enterprise control, or every piece of evidence tied to a technology.
  • Inheritable — reuse proven enterprise control evidence and tailor from a known-good baseline.
  • Consistent — the same enterprise control is described the same defensible way across every authorization.
Compounding value: the tenth assessment is faster and stronger than the first — because it stands on nine that came before it, instead of a blank sheet.
Where it delivers

Faster assessments, higher quality

The goal isn’t to cut corners on security — it’s to remove the coordination and copy-paste that surround it, so assessments stop being the bottleneck that delays delivery. Time comes back to both assessors and project teams, who can return to the implementation work the assessment exists to protect.
