Estate sprawl
Twelve acquisitions in eight years leaves four EDR vendors, three SIEMs and a directory forest nobody fully maps. Coverage gaps live in the seams between them, not inside any single tool.
Solutions for large enterprise
Global enterprises do not have one estate — they have forty. Guardian Sentinel gives you a single detection fabric, delegated governance for every business unit, and region-pinned data handling, without asking you to rebuild the environment you already run.

The enterprise reality
Scale does not simply multiply the problem — it changes its shape. These are the four failure modes Guardian was engineered around, drawn from deployments across banking, pharmaceuticals, industrial manufacturing and global logistics.
Twelve acquisitions in eight years leaves four EDR vendors, three SIEMs and a directory forest nobody fully maps. Coverage gaps live in the seams between them, not inside any single tool.
The German works council, the Brazilian subsidiary and the US federal division each need different policy, different retention and different visibility — enforced, not promised in a spreadsheet.
Telemetry that crosses a border creates a legal event. Most platforms solve this with a regional console per jurisdiction, which destroys the cross-estate correlation you bought the platform for.
Your board asks whether the company is safer this quarter than last. Alert counts and MITRE heat maps do not answer that question, and building the answer by hand eats a week of your analysts' time.
One fabric, every surface
Sentinel ingests from mainframe to Kubernetes to the OT cell controller on a plant floor, normalises everything to one schema, and correlates across all of it before a human ever sees an alert.
Sentinel runs alongside incumbent EDR and SIEM during migration. Most enterprises retire their legacy stack in waves over two to three quarters, not in a single cutover weekend.
Windows, macOS, Linux, Solaris, AIX, Android, iOS, Kubernetes, ESXi, and legacy Windows Server 2012 R2 estates that cannot yet be retired.
Edge sites on satellite or 4G backhaul use local aggregation and adaptive sampling, typically holding telemetry under 40 MB per host per day.
Mergers & acquisitions
Day-one visibility is the difference between inheriting a business and inheriting a breach. Guardian's M&A integration programme is a fixed-scope engagement run by our enterprise delivery team alongside your integration management office.
Sentinel agents push through the target's existing management tooling — Intune, SCCM, Jamf, Ansible or a signed installer. Unmanaged assets surface through passive network discovery within the first 72 hours, including the shadow estate the target's own CMDB never recorded.
A retrospective hunt runs across all collected telemetry and available historical logs, looking for pre-existing implants, dormant persistence and credential material already in adversary hands. Roughly one acquisition in five surfaces a live finding here.
The acquired estate is placed in its own governance scope with your baseline policy applied in monitor mode, so nothing breaks on day one. Identity trust between the two directories is brokered rather than merged until both sides are clean.
Policy moves from monitor to block, response playbooks are enabled, and the estate is folded into your existing reporting hierarchy — one more row in the same board pack, not a separate conversation.
Multi-region data residency
Guardian separates the data plane from the control plane. Raw telemetry, files and forensic artefacts are stored and processed only in the region you assign to that entity. Detection metadata — never the underlying content — is what makes global correlation possible.
Residency is set per legal entity, not per tenant. A single Guardian tenant can hold a German subsidiary pinned to eu-central, a US federal division inside the FedRAMP High enclave, and an APAC joint venture in ap-singapore simultaneously.
Delegated governance
Enterprise security is a negotiation between central standards and local autonomy. Sentinel encodes that negotiation in the product rather than in a policy document nobody reads.
Build a tree that mirrors your organisation: group, division, legal entity, site, business unit. Policy set at any level flows downward automatically. Local administrators can loosen only what the level above explicitly marks as delegable, and every override is recorded with a justification and an expiry date.
Central security teams keep a permanent read path into every scope for detection purposes, even where local administrators cannot see one another's data — the arrangement most European works councils will actually sign.
Twenty-two built-in roles cover the common split between SOC analyst, incident responder, threat hunter, IT operations, auditor and executive viewer. Custom roles compose from 340 discrete permissions, and any role can be conditioned on attributes such as scope, time window, source network or approved change ticket.
Break-glass elevation is supported with mandatory dual approval, a hard time limit and an immutable session recording that your internal audit function can replay.
Every policy, detection rule and response playbook is exportable as versioned YAML. Enterprises typically run configuration through their existing GitOps pipeline, with Guardian's Terraform provider applying approved changes and a policy simulator estimating blast radius before anything reaches production.
Rollback is a single revision revert, applied estate-wide in under two minutes.
An append-only audit ledger records every administrative action, data access and policy change with actor, source, justification and before-and-after state. Records stream to your own archive in real time and are retained in-platform for up to seven years.
Read-only regulator and external-auditor accounts can be scoped to a single entity and a fixed date range, so an examination in one jurisdiction never exposes another.
When a division is sold, its scope can be extracted into a standalone tenant with its telemetry, policy, historical detections and audit trail intact — and the parent's data removed. The separation is a supported, scripted operation, not a professional-services rescue project. Divestiture separations have been completed inside a 10-day window.
Enterprise risk posture — trailing eight quarters
Executive & board reporting
Sentinel maintains a continuously computed exposure index per entity, built from control coverage, unresolved critical findings, identity hygiene, dwell-time performance and validated attack-path reachability.
Dedicated support model
Enterprise agreements ship with a standing account team rather than a ticket queue. Every member is briefed on your architecture, your change calendar and your escalation expectations at onboarding, and stays with the account.
Your single owner for roadmap, escalation and quarterly reviews. Named, time-zone aligned, and backed by a documented deputy.
Optional on-site or embedded engineer, two to five days a week, tuning detections and running hunts inside your environment.
Pre-signed incident response retainer with contracted hours held in reserve and a 15-minute callback on a declared major incident.
A Guardian vice-president accountable for the relationship, who joins the annual review and owns any commercial escalation.
| Severity | Definition | First response | Update cadence | Escalation path |
|---|---|---|---|---|
| Sev 1 | Active intrusion, platform outage, or a control failure that leaves production unprotected. | 15 minutes, 24 / 7 | Every 30 minutes | Duty director paged at 60 minutes; VP engineering at 3 hours. |
| Sev 2 | Major functionality degraded, detection gap on a critical asset group, no viable workaround. | 1 hour, 24 / 7 | Every 4 hours | TAM engaged at 4 hours; duty director at 12 hours. |
| Sev 3 | Non-critical defect, tuning request, or a question that blocks a scheduled change. | 4 business hours | Daily | TAM reviews weekly; customer may promote severity. |
| Sev 4 | Advisory, feature request, documentation or general how-to. | 1 business day | Weekly | Tracked on the quarterly roadmap review. |

Enterprise agreements include unlimited authorised contacts, a private Slack or Teams channel bridged to our duty roster, and a 30-day advance notice window on any change that could affect your integrations. Compare all support plans.
We consolidated four endpoint vendors and two SIEMs into Guardian across 61 legal entities in eleven months. The part I did not expect was the governance model — for the first time our German and Brazilian teams could run their own policy without us losing group-level visibility.
Guardian's enterprise practice supports organisations from 5,000 to 400,000 seats across 142 countries, including 43 members of the Fortune 100 and eleven of the world's twenty largest banks by assets.
