Incident Response & Business Resumption
Contain the threat.
Resume the business.
Then prove it is safe and keep it that way. Cyrenity Cyber brings senior responders, AI-accelerated investigation, and hands-on recovery into one coordinated response, from the first call to a validated return to operations.
Trusted by organizations that demand excellence
What we handle
Response for the full incident lifecycle.
One coordinated team from first evidence to safe return to operations, working alongside your counsel, insurer, and specialist partners where needed.
Emergency incident response
Around-the-clock triage, incident command, forensic investigation, containment, eradication, and executive status reporting from the first hours.
Ransomware and extortion response
Rapid scoping, evidence preservation, backup and restoration planning, data-exposure analysis, and coordination with counsel, insurers, and specialist partners.
Business resumption
Clean recovery planning, identity restoration, backup validation, rebuild support, application sequencing, and return-to-service validation.
Cloud, identity, SaaS, and email
Investigation of credential theft, session and token abuse, malicious OAuth grants, cloud persistence, business email compromise, and payment fraud.
AI systems incident response
Investigation of prompt injection, unauthorized agent actions, MCP and tool misuse, RAG and memory poisoning, and model or pipeline compromise.
Compromise assessment
Evidence-based answers when something looks wrong but a breach is not confirmed, with a direct path to full response if we find an active intrusion.
Recovery workstreams
Every resumption is tracked against the same workstreams, so leadership always knows what is safe, what is running, and what is next.
- Incident command and a single source of truth
- Identity and privileged-access recovery
- Backup viability and data restoration
- Server, endpoint, virtualization, and cloud rebuilds
- Logging and monitoring restored before reconnection
- Executive, counsel, and insurer status reporting
How we respond
Investigation and recovery, running in parallel.
Waiting for a final forensic report before restoring anything extends downtime. We run both tracks at once, coordinated by one incident command, so the business comes back while the threat is still being run to ground.
Mobilize
Secure out-of-band communication, incident command, decision rights, counsel and insurer pathways, and immediate safety actions in the first hours.
Threat response
Stop the attacker and establish defensible facts.
Scope
Identify affected identities, systems, and data, and where the attacker still has reach.
Contain
Isolate assets, revoke compromised access, and stop lateral movement without destroying evidence.
Investigate
Reconstruct the entry point, timeline, persistence, and data exposure across the environment.
Eradicate
Remove persistence, close the path of entry, and rotate credentials, keys, tokens, and sessions.
Business resumption
Bring back what matters first, cleanly.
Prioritize
Map technology to the services that keep revenue, safety, and daily operations running.
Restore
Recover clean identity first, then critical applications, data, and user access in planned waves.
Validate
Confirm integrity, monitoring, and business-owner acceptance before anything reconnects.
Reconnect
Bring the estate back in controlled stages while watching for any return of the threat.
Safe return to operations
Declared only when agreed containment, restoration, validation, and business criteria are met. Then you receive the evidence-backed record, lessons learned, and a resilience roadmap.
Business resumption
Recovery is not complete until the business can operate.
Clean endpoints are not the finish line. We map technology to the services your organization depends on, recover them in waves, and track dependencies and blockers until operations are back.
Leadership gets a current view of what is safe, what is running, what remains at risk, and what happens next.
What "resumed" means to us
- Priority business services are identified and sequenced by operational impact.
- Clean identity and administrative control are restored.
- Critical applications, data, and communications are available.
- Restored systems pass both technical and business-owner validation.
- Monitoring confirms the attacker has not re-established access.
- Executives, counsel, insurers, and key partners have decision-ready status.
- There is an agreed path from temporary workarounds to a stable target state.
Response in the AI era
Machine speed, without machine-speed mistakes.
AI is compressing the attack cycle. We use it to move faster, and keep accountable people in command of every consequential decision.
AI-accelerated
Automation collects and correlates evidence across tools, reconstructs timelines, enriches indicators, and keeps reporting current while responders work.
Expert-commanded
Senior responders validate material findings and own containment and recovery decisions. High-impact actions follow rules of engagement you approve.
Evidence-backed
Every finding ties to evidence and every action is logged. No AI-generated conclusion is treated as forensic fact until a responder confirms it.
When the AI system is part of the incident
Endpoint and application logs cannot always explain an AI incident. We reconstruct what the model received, what the agent decided, which tools and data it touched, which identity authorized it, and what changed downstream.
Explore AI securityEvidence we preserve and analyze
- Prompts, outputs, sessions, and system instructions
- Agent decision chains and tool-call history
- MCP servers, plugins, connectors, and API paths
- Retrieval sources, vector stores, and agent memory
- Model, configuration, and pipeline integrity
- Agent identities, tokens, and permissions
Containment can mean disabling an agent or model endpoint, revoking its access, quarantining a data source, suspending a workflow, or rolling back to a trusted state, followed by safe revalidation before redeployment.
When to call
If this is happening, we have been here before.
Every incident is different. These are the situations organizations most often bring to us.
Ransomware has disrupted core systems
Containment, forensic scoping, and clean recovery have to run at once, while leadership needs a clear plan for bringing revenue-critical services back first.
An identity or cloud compromise is still active
Tokens, sessions, OAuth grants, privileged roles, SaaS access, and cloud persistence must be found and revoked without locking the response team out.
Funds or sensitive communications are at risk
Mailboxes, forwarding rules, identities, and payment workflows need fast investigation to stop fraud and establish what the attacker saw.
An AI agent took an action nobody authorized
We preserve prompts and context, identify the initiating identity, reconstruct tool calls, contain connected systems, and determine downstream impact.
Something looks wrong, but nothing is confirmed
A focused compromise assessment establishes defensible facts before you trigger a larger crisis process, and escalates straight to response if we find an intrusion.
Incident response FAQ
Incident response, answered.
What organizations most often ask about how we respond, recover, and work with counsel, insurers, and AI systems.
Incident response & resumption
Do you work with our cyber insurer and breach counsel?
Yes. We coordinate with your insurer, broker, and breach counsel from the start, keep technical work aligned with counsel's direction, and maintain the defensible record that claims and legal processes rely on. Coverage and vendor approval remain subject to your policy and carrier.
Can investigation and recovery happen at the same time?
Yes, and they should. We preserve the evidence the investigation needs and hold containment while clean recovery proceeds in order of business priority, so you are not waiting on a final forensic report to get critical services back.
Will AI make decisions during our incident?
AI speeds up evidence collection, correlation, hunting, and documentation. Senior responders validate material findings, and consequential containment or restoration actions follow authorization rules you agree to in advance.
Can you investigate an AI agent or LLM application?
Yes, when the right telemetry and access are available. Relevant evidence includes prompts, model details, retrieved context, agent memory, tool calls, MCP activity, identities, permissions, outputs, and downstream system changes.
Do we have to replace our current security tools?
No. We respond using the telemetry and controls you already have, and deploy additional collection tools quickly only where visibility falls short.
When is the incident considered over?
When agreed containment, eradication, restoration, validation, monitoring, legal, and business criteria are met, not simply when malware is removed. We document each criterion so leadership can declare the return to operations with confidence.
How is this different from incident readiness?
Incident readiness is the preparation before an incident: tabletop exercises, response plans, and a retainer. Incident response and business resumption is the work during and after one. Most organizations pair them, so the first call starts with decisions instead of discovery.
