Sanal Çekirdek

See the threat. Contain the impact. Recover with confidence.

Cyber resilience is a security approach that connects protection, detection, response and recovery in one program to limit the business impact of an attack. Sanal Çekirdek applies this approach because fragmented alerts, unclear ownership and untested recovery plans can magnify that impact.

Risk and security architecture

We assess assets, identities, data, applications and supplier dependencies in the context of business impact. Zero Trust is applied as a set of design decisions—verification, least privilege, segmentation, continuous visibility and controlled access—not as a product label.

  • Asset and attack-surface visibility
  • Identity and privileged access
  • Network and workload segmentation
  • Cloud, data and application controls

Detection and managed security services

Instead of centralizing logs without context, we connect data sources to meaningful use cases, prioritization and response workflows. The SOC, MDR or XDR model is shaped around the existing team, risk profile, service hours and required depth of expertise.

  • Use-case and detection engineering
  • Alert enrichment and prioritization
  • Threat hunting and event correlation
  • Incident records, reporting and improvement

Incident response and cyber recovery

Decision rights, isolation steps, evidence preservation and recovery validation are defined before an incident occurs. In a ransomware scenario, available backups are not enough; identity, networking and management layers must also be recoverable in a trusted state.

  • Incident response plan and role cards
  • Isolation and communication workflows
  • Clean-room and validation approach
  • Tabletop and technical recovery exercises

Authorized, evidence-led execution

Penetration testing, attack simulation and related activities are performed only with written authorization, a defined scope, an agreed window and stop conditions. Findings are reported with evidence, business impact, practical remediation and retest steps.

  • Scope and rules of engagement
  • Safe testing and emergency stop
  • Risk-based finding priority
  • Remediation validation and closure

How we work

  1. Discovery and current-state assessment
  2. Target architecture and control design
  3. Pilot, migration or modernization plan
  4. Go-live against acceptance criteria
  5. Monitoring, managed services and continual improvement

How success is measured

  • Validation and response time for critical alerts
  • Coverage across identities, assets and log sources
  • Closure time for high-risk findings
  • Recovery exercise criteria and residual risk

Frequently asked questions

Are SOC, MDR and XDR the same thing?

No. A SOC is an operating and team model; MDR is a managed detection and response service; XDR is a technology approach that correlates telemetry across security layers. The right combination depends on the organization's current capability.

What is required before a penetration test?

Targets, IP and application scope, permitted methods, testing window, contacts, data-handling conditions and the emergency stop process must be approved in writing. Work does not begin without the required authorization and documentation.

Is backup enough for cyber resilience?

No. Backups must be isolated from the attack path, identity and management layers must be protected, a clean recovery point must be selected, residual compromise must be checked and the recovery order must be tested.
