Embedded Security Support
Embedded Security Support is an embedded service engagement for teams that need senior security leadership alongside hands-on review. Sigma Prime works with engineering and operational leads on design review, release risk, audit readiness, vulnerability triage, and security decision-making. For some teams this also serves as an external vCISO-style role: a senior security counterpart who helps leadership make clearer calls on launch risk, escalation, and security ownership.
Where it fits.
This engagement fits teams that need recurring security ownership between major audits rather than a single point-in-time review.
-
01
Embedded security review for active development. Review design changes, pull requests, invariants, threat assumptions, and release-blocking risks as the system evolves.
-
02
vCISO-style security leadership. Help set priorities, shape escalation paths, guide incident preparation, and provide a senior security voice in ongoing product and operational decisions.
-
03
Audit-readiness support. Prepare protocol, smart contract, infrastructure, or frontend scope before a formal external audit begins.
-
04
Finding lifecycle management. Help teams reproduce, prioritize, remediate, and regression-test findings without losing the original threat model.
-
05
Use of automation where it helps. Embed tools into daily review and triage workflows when they improve codebase navigation, context retention, static-analysis triage, or other repetitive reviewer tasks.
Embedded operating model.
Embedded Security Support does not follow the same six-phase model as a fixed-scope audit. We scope the engagement around the product surface, release cadence, and the level of embedded support your team needs. Some teams need a short audit-readiness sprint; others need recurring security leadership over multiple releases.
We use automation where it improves the review process and can embed it into day-to-day workflows when that helps the team move faster. It is a tool that supports Sigma Prime engineers rather than a substitute for their judgment, threat modelling, or remediation advice.
This is separate from Secstant, our security tooling product under development. Embedded Security Support is the service model; tooling may support that work over time, but the engagement is led by engineers.
How embedded security support works.
This is not a standing audit report
A fixed-scope audit gives a clear report for a clear code snapshot. Embedded Security Support is different. It is useful when a team needs recurring security input while design, implementation, and release planning are still moving. The output is review notes, finding triage, readiness work, and concrete changes to the security workflow.
The vCISO element is practical, not ceremonial
For some teams, the gap is not another line-by-line review. It is the absence of a senior security counterpart who can make risk tradeoffs legible, challenge weak release assumptions, and help leadership decide what needs to block a launch. The vCISO aspect of this engagement fills that role without pretending to be a full internal security department.
Automation supports the process
Automation can help reviewers navigate a large codebase, preserve context, group static-analysis output, and compare new changes against old findings. It does not own the threat model, severity call, exploitability judgment, or remediation advice. Those remain Sigma Prime engineer responsibilities.
Where this model fits
-
Teams preparing a complex scope before a formal audit window.
-
Protocols shipping frequent upgrades that need recurring security review between audits.
-
Engineering teams with findings to reproduce, prioritize, fix, and regression-test.
-
Leadership teams that need a credible external security counterpart while building internal process and ownership.

Frequently asked questions.
-
Is this a replacement for a formal audit?
No. It is useful before, between, or after audits. It can reduce audit risk by improving readiness, but a formal audit still has a clearer scope, report, and review window.
-
Is the work performed by AI?
No. Sigma Prime engineers own the security judgment. Automation can help with navigation, triage, and repetitive workflow tasks, but it does not replace expert review.
-
How is this different from Secstant?
Embedded Security Support is a service engagement with our team. Secstant is product tooling under development.
