Cyber Resilience and Recovery
Backups alone do not bring critical systems back after an attack. Silex designs, builds, and operates isolated recovery environments, and proves that recovery works with structured tests and after-action reviews.
The recovery lifecycle
- 01 Recover
- 02 Eradicate
- 03 Harden
- 04 Validate
- 05 Reconnect
Isolated recovery environment
Four zones between an attack and recovery.
Silex designs isolated recovery environments on the assumption that production is compromised. Recovered systems move through four zones, and each move requires passing a control point.
Recovery lifecycle
Five phases before a system goes back into service.
Every recovered workload completes the same five phases. The architecture, the orchestration platform, and the runbooks enforce the sequence, so recovery does not depend on judgment calls during a crisis.
- 01RecoverClone the chosen recovery point from immutable snapshots into the air-gapped Validation Zone.
- 02EradicateScan for malware, rogue accounts, and persistence, and remove them before anything moves on.
- 03HardenPatch, reset credentials, and close the paths the attacker used.
- 04ValidateConfirm that each application works and that its data is intact.
- 05ReconnectReturn systems to service and reconnect users only after authorization.
Eradication is the difference.
Traditional disaster recovery restores a copy and assumes it is clean. Cyber recovery assumes an attacker may have been present long before the attack started, so Silex plans eradication at scale and expects it to take more than one pass.
Orchestrated, not improvised.
Recovery orchestration runs the sequence from one interface: snapshot clones, volume mounts, and virtual machines powered on with corrected network settings inside isolated VLANs.
Recovery testing
Three test tiers, each with an after-action review.
Each tier exercises more of the lifecycle than the one before it. After every test, Silex and your leadership review what worked, what did not, and what changes before the next test.
| Tier | What it exercises | Lifecycle coverage |
|---|---|---|
| TierSmoke testTier 0 | What it exercises Core critical systems only. Confirms replication integrity, snapshot mounts, and the boot sequence from the recovery environment. | Lifecycle coverage RecoverEradicateHardenValidateReconnect |
| TierMulti-point-in-time testTier 0+1 | What it exercises The full in-scope workload set, recovered from several candidate recovery points. Tests forensic recovery-point selection and cross-workload sequencing. | Lifecycle coverage RecoverEradicateHardenValidateReconnect |
| TierIncident simulationFull test | What it exercises Simulates an attack from an unknown vector and runs the full lifecycle, through authorized reconnection of end users, with security validation at each stage. | Lifecycle coverage RecoverEradicateHardenValidateReconnect |
Cyber Recovery Maturity Model
Know where your recovery stands.
Silex measures recovery programs against a five-level Cyber Recovery Maturity Model. Each level is a different state of readiness, with measurable differences in recovery time and reliability.
The maturity assessment places you on the scale and delivers a roadmap to the next level. The model then guides the architecture, the testing program, and the automation work.
Between tests
Continuous validation keeps the environment ready.
A recovery environment drifts as production changes. Silex automation checks readiness between test cycles and reports the gaps before an incident finds them.
Frameworks and evidence
Evidence that recovery works.
- HIPAA contingency planning, including testing and revision of the plan
- NIST Cybersecurity Framework 2.0 Recover function
- Test records and after-action reviews for auditors, cyber insurers, and board risk committees
Silex designs and operates isolated recovery environments for healthcare, tested through structured recovery exercises.

Questions buyers ask
Questions
How is an isolated recovery environment different from backups and disaster recovery?
Backups and disaster recovery assume the copy is clean and the environment can be trusted. An isolated recovery environment assumes the attacker may still be present. It keeps immutable copies out of production's reach, restores into an air-gapped zone, and removes malware and validates systems before they reconnect.
What does air-gapped mean in this design?
The Validation Zone has no network path to production or to external networks. Recovered workloads are scanned, cleaned, and tested there before they move to the Recovery Zone.
How often should we test recovery?
Silex sets a schedule with you for each test tier. Smoke tests are quick and can run often, while full incident simulations need more coordination across teams. Continuous validation checks the environment between tests.
Does this work with our current backup platform?
Yes. Silex builds the storage layer on Dell PowerMax and PowerProtect and works with Cohesity, Commvault, and Zerto. Backup-based recovery covers workloads that fall outside storage replication.
How do staff keep working during an incident?
The End-User Zone gives staff virtual desktops for recovered applications. A separate Zero Trust access platform controls that access, and a person can reach production or the recovery environment, but not both at once.
