Technology, software & SaaS
For a software company, a breach is not an operational problem — it is a product problem, a renewal problem and a fundraising problem. Guardian Sentinel secures the path from a developer's laptop to a production tenant: source code, build pipeline, artefact registry, runtime and the isolation boundary your customers are trusting.
Source code & CI/CD
An attacker who compromises production reaches one environment. An attacker who compromises your build reaches every environment you ship to, signed, with your release notes attached. Guardian instruments each stage of the software factory and treats a change in build behaviour with the same seriousness as a change in production behaviour.
Engineers will route around a security agent that costs them build time. Guardian's macOS and Linux sensors exclude toolchain directories from synchronous inspection by default, add a measured 1.8% to a cold Rust build, and never quarantine a file mid compile. Where a real detection fires, the developer gets an in-context explanation rather than a silent block and a support ticket.
Endpoint securityA CI runner holds cloud credentials, registry write access and your signing identity. Guardian treats it as a tier-one asset: runtime detection inside the job, an egress allow-list so a compromised dependency cannot phone home, and an alert the moment a build step executes something that was not in the workflow definition.
Cloud & workload securityGuardian scans commits pre-receive, scans the history you already have, and — more usefully — validates whether a discovered credential is live. A revoked key in a 2019 commit is noise. A live production token in a public fork is an incident, and Guardian opens it with the revocation action already staged.
Data protectionMulti-tenant isolation
Every SaaS security review eventually arrives at the same question: how do you know tenant A cannot read tenant B's data? “Because the query includes a tenant ID” is an answer that has failed publicly many times. Guardian gives you evidence instead of an assertion.
Guardian learns the normal shape of data access per service and flags the query path, API route or background job that touches more tenant partitions than its function requires — the signature of both a broken authorisation check and an active enumeration attempt.
For per-tenant Kubernetes namespaces or per-tenant clusters, Guardian enforces and verifies the network policy that separates them, and alerts on any pod that acquires a service account, mount or route belonging to a different tenant.
Where you offer per-tenant encryption keys or customer-managed keys, Guardian confirms the key actually in use on each write path matches the tenant's declared key — because key configuration drift is invisible until a customer audits it.
Your support engineers can impersonate a customer, and your customers know it. Guardian records every impersonation session with the ticket reference, the data viewed and the duration, and can expose that log to the affected tenant directly.
Customer trust & attestations
Enterprise buyers gate on security review long before they gate on features. The companies that win those cycles are not the ones with the most controls — they are the ones who can evidence the controls in a week rather than a quarter.
| Framework | Typically blocking at | The hard part | What Guardian supplies |
|---|---|---|---|
| SOC 2 Type II | First six-figure enterprise deal | Proving controls operated continuously across the observation window, not on audit day | Continuous control evidence with timestamps, exported per trust services criterion |
| ISO 27001 & 27017 | First serious European or APAC enterprise deal | Annex A coverage, risk treatment records and management review inputs | Control mapping, asset inventory and incident register in the structure the auditor expects |
| SLSA Level 3 | When your buyers ship regulated software themselves | Non-falsifiable build provenance and isolated, ephemeral build environments | Provenance capture at the runner, artefact attestation verification and drift alerting |
| NIST SSDF (SP 800-218) | US federal and federal-adjacent sales | Evidence for the secure software attestation form, signed by an executive | Practice-level evidence for PO, PS, PW and RV groups, generated from live pipeline telemetry |
| FedRAMP | Direct US government sale | Boundary definition, continuous monitoring and 325 controls with an authorising official | FedRAMP High deployment option and ConMon telemetry that maps to the monthly deliverable |
| CSA STAR & CAIQ | Any deal where procurement uses a standard questionnaire | Keeping 261 answers accurate as the product changes weekly | Answer library backed by live control state, so a drifted answer is flagged rather than shipped |
Scroll the table sideways to see every column.
Guardian can publish a live subset of your control state — patch currency, MFA coverage, incident count, uptime — into your own trust centre, so prospects self-serve the answers instead of queuing behind your solutions engineer.
Your customers hold you responsible for your vendors. Guardian monitors the SaaS applications and OAuth grants inside your own estate and flags the ones that acquired production data access without a review.
IntegrationsMost enterprise contracts commit you to notification inside 24 or 48 hours with specifics. Guardian's incident narrative gives you the affected-tenant list and the timeline in hours, so the clause is survivable.
Incident responseScaling without re-platforming
The tooling that suits a forty-person startup is usually abandoned at three hundred and torn out at a thousand. Guardian is one platform across all three, and the things that change are configuration, not architecture.
There is no security team. There is one engineer who cares, and a founder who has just been sent a 214-question spreadsheet by a prospect. The priorities are laptop coverage, MFA everywhere, secret scanning and a defensible answer about production access.
Guardian deploys in an afternoon: agents by MDM, cloud connected read-only, source control connected by app install. Managed detection carries the on-call, because a four-person engineering team cannot also be a SOC. This is the same configuration described on the small business page, and it costs accordingly.
Now there are staging environments nobody owns, three cloud accounts created during a hackathon, a data team with production read access, and a compliance deadline. The first security hire spends month one building an inventory by hand unless something already has it.
Guardian's estate model — assets, identities, repositories, pipelines, cloud resources and the relationships between them — is that inventory, and it is already populated on day one because the sensors have been running since the seed stage. Policy graduates from “alert someone” to environment-specific enforcement.
Product lines diverge, an acquisition arrives with its own stack, a regional deployment is required for a European customer, and the security team is now eleven people organised into functions. Delegated administration matters, and so does the ability to give the acquired company its own console view without merging identity systems on day one.
Guardian's multi-tenant governance handles both: business units get scoped consoles, shared detection content, and roll-up reporting for the CISO. See enterprise for how that model works at the largest scale.
Diligence tells you what the acquired company documented. Guardian tells you what it actually runs. Deploying sensors during the integration window typically surfaces two to three material findings — an unrotated shared credential, an internet-exposed admin interface, a data store nobody named — inside the first fortnight.
Because the acquired estate can run as its own scope under your contract, you get visibility before you get integration, which is the correct order.
How it fits your engineering workflow
A finding that lands in a security console is a finding that waits. A finding that lands in the pull request, the terminal or the incident channel gets fixed in the same session.
Guardian comments on the specific line, explains the exploitability in your codebase rather than in the abstract, and suppresses the finding automatically if the code path is unreachable from any entry point.
Policy gates are declared as code, evaluated in the build, and return a machine readable verdict. Break-glass overrides exist, are logged with the person and reason, and appear in the weekly report.
Guardian posts the narrative into the channel your on-call already lives in, with the evidence attached and the containment action offered as a button rather than a runbook step.
Everything the console does is available over a documented REST and GraphQL API with webhooks, so the parts of the workflow you have already automated stay automated.
We closed our largest deal in company history on a security review that took eleven days instead of the usual quarter. Their assessor asked for evidence that our build environment was isolated and our artefacts were attested. We exported it from Guardian while she was still on the call. That is worth more to me than any dashboard.
Connect a repository and a cloud account in a thirty-minute session, and we will pick a running container in your environment and resolve it to the commit, the reviewer and the build that produced it — in front of you. If we cannot, that is worth knowing too.
