Incident response for US businesses

Cyber incident response for US businesses: triage, contain, recover, document.

When a cyber incident happens, the first hour determines the recovery cost. Our incident response engagement provides 24/7 on-call IR engineers, tested playbooks for ransomware, business email compromise, and data breach, forensic preservation discipline, evidence packs your breach counsel and cyber insurer will ask for, and recovery support. Retainer model for ongoing readiness, or emergency engagement on active incidents, delivered remotely into your environment.

IR engagement scope

Eight IR capabilities under one engagement.

Incident response is not just "we will help when something happens". It is a structured engagement with retainer access, tested playbooks, drill cadence, forensic discipline, and recovery support, built around the notification and evidence obligations US businesses actually carry. We deliver all of it.

24/7 IR escalation access

A dedicated escalation route for retainer clients, answered around the clock. P1 incidents reach an incident-trained on-call engineer within five minutes, not a helpdesk queue. Triage starts on the first contact.

Tested IR playbooks

Written runbooks per incident type: ransomware, business email compromise, data breach, insider threat, account compromise, DDoS. Reviewed quarterly, validated through tabletop exercises with your team.

Triage and containment

First-hour priorities: scope assessment, system isolation, credential resets, forensic preservation start. Containment actions stop the spread while preserving the evidence your counsel and insurer will need.

Forensic preservation and investigation

Disk imaging, memory capture, and log preservation following chain-of-custody discipline. Findings documented so they hold up for law enforcement referral, insurance claims, and litigation your counsel may anticipate.

Breach notification support, through counsel

Every US state has a breach notification statute, public companies carry SEC disclosure obligations for material cybersecurity incidents, and sector rules such as HIPAA add their own. We produce the technical facts: what was accessed, when, and whose data. Your breach counsel remains the legal author of every notification decision; we supply the substance.

Recovery and restoration

Recovery from immutable backups, system rebuild guidance, compromised-credential rotation, and post-incident hardening. Coordinated to minimize business disruption while the investigation continues.

Communication plan support

Staff communications, customer communications, vendor communications, board briefings. Templates for each audience, tone calibrated to incident severity, with legal review coordinated through your counsel.

Quarterly tabletop exercises

A simulated incident walked through end to end with leadership. Tests the playbook, validates the communication chain, and finds the gaps in the response process before a real incident exposes them.

Why businesses choose us for IR

Four reasons IT leaders engage GR for incident response.

Playbooks built from real response work, not templates

Our runbooks come from incidents our engineers have actually worked: ransomware containment, business email compromise with funds in motion, data breach investigations. The people who answer your escalation have run these procedures under pressure, not just written them.

5-minute P1 engagement, 24/7

For retainer clients, a P1 escalation reaches an on-call IR engineer within five minutes, around the clock including weekends and holidays. Triage starts immediately. Time-to-containment is the metric that matters most in IR; we minimize it.

Retainer or emergency

Retainer engagement provides drill cadence, pre-positioned playbooks, and the fastest engagement path. Emergency engagement is available on active incidents with no advance preparation, scoped and quoted on contact. Most clients move from emergency to retainer after their first incident.

Coordinated with counsel, insurer, and communications

IR is multi-stakeholder. We coordinate with your breach counsel, your cyber insurance carrier and its panel requirements, and your communications team, so the response is integrated rather than fragmented. Where your policy names approved vendors, we work within that structure.

Incident types we handle

Six incident types with tested playbooks.

Ransomware

Active encryption, ransom demand, lateral-movement containment, backup-led recovery.

BEC and executive fraud

Wire-transfer fraud, executive impersonation, vendor-account takeover. Time-critical if funds are in motion.

Data breach

Sensitive data exfiltrated or exposed. State notification analysis through counsel, customer-communications strategy.

Insider threat

Employee or contractor misuse. Discovery, containment, evidence preservation for HR and legal action.

Account compromise

Credentials stolen, account taken over, downstream actions. Containment, rotation, forensics.

DDoS and availability attacks

Service availability disrupted. Coordinated with your ISP and CDN provider for mitigation.

How an IR engagement runs

Retainer setup and incident response cadence.

  1. 1

    Retainer setup

    2-4 weeks

    Workshop with security and operations leads. Map the current environment, agree playbook scope, establish the escalation route, and designate IR contacts on your side, including your breach counsel and insurer details.

  2. 2

    Playbook customization

    2-3 weeks

    Customize generic playbooks to your environment: which systems are crown jewels, which notification obligations apply, which people to contact at 3am, which vendors and carriers to notify.

  3. 3

    First tabletop exercise

    1 day

    A live tabletop with leadership: a simulated ransomware or BEC scenario walked through end to end. The playbook is tested, the communication chain validated, and the gaps identified.

  4. 4

    Quarterly drill cadence

    Continuous

    Quarterly tabletop exercise, annual full simulation, playbook updates as your environment evolves, and contact verification so the plan stays current between incidents.

Incident response FAQ

What buyers ask before engaging.

Retainer is pre-positioned: customized playbooks, regular drills, a dedicated escalation route, and pre-agreed scope. It gives the fastest engagement when an incident happens. Emergency is reactive: no advance preparation, scoping done under pressure, and a longer path to an engineer, typically hours rather than minutes, because contracts and access have to be established mid-incident. Most clients move from emergency to retainer after one real incident.

Yes. Our on-call rotation covers 24/7/365 including weekends and US holidays. For retainer clients, P1 escalations reach an incident-trained engineer within five minutes. Delivery is remote, which is how modern IR works in practice: containment, forensics, and recovery actions are executed in your tenant and infrastructure over secure remote access, without waiting for anyone to travel.

We are a remote-first team and we respond remotely, which is faster than any travel-based model for the actions that matter in the first hours: isolation, credential resets, log preservation, and tenant-level containment. Where an incident genuinely requires physical hands, such as seizing a specific device, we coordinate with your local staff or a local resource and direct the work.

Every state has its own breach notification statute, with differing definitions, thresholds, and timing, and sector rules such as HIPAA add federal obligations. Public companies also carry SEC disclosure obligations for material cybersecurity incidents. Because these are legal determinations, notification decisions belong with your breach counsel. Our role is the technical substance: establishing what was accessed, when, and whose data, in a form counsel can act on quickly.

We coordinate. For most US businesses that means an FBI field office or the IC3 reporting route for cybercrime, and for wire fraud the fastest lever is your bank plus law enforcement engagement, which we help initiate immediately. We provide the technical evidence pack. We do not replace your legal counsel; we are the technical witness and incident coordinator.

We strongly advise against paying. Payment funds further criminal activity, does not guarantee decryption, and can create sanctions exposure where a payment touches a sanctioned entity, which is a question for your counsel, not a technical one. If operational pressure makes payment unavoidable, we bring in a specialist ransomware-negotiation firm and law enforcement, and we provide the technical assessment of decryption viability. We do not negotiate with criminal groups ourselves.

An annual retainer with a per-incident draw against included hours, scoped per engagement to your size and risk profile. Most retainers include the tabletop exercises, drill preparation, and capacity for a moderate incident. Larger incidents draw down a buffer or extend at pre-agreed retainer terms, which is exactly the negotiation you do not want to have mid-incident.

It depends on incident type and severity. Active ransomware: containment typically within hours of engagement. BEC with funds in motion: same hour, with bank coordination started immediately. Data breach: containment within hours, then weeks of forensic work. We track time-to-containment as a key engagement metric, because it is the number that drives total incident cost.

Yes, and it should be set up before an incident. Many policies require notice to the carrier before engaging vendors, some name approved IR panels, and most require specific evidence for a claim. During retainer setup we record your carrier, policy notification route, and panel requirements in the playbook, and during an incident we capture evidence, timelines, and recovery documentation in the form carriers ask for.

It adds a disclosure workstream on top of the technical response. Public companies are subject to SEC disclosure obligations for material cybersecurity incidents, and materiality is a determination your counsel and officers make, not your IT team. What we change operationally: the evidence and impact assessment is produced with that determination in mind from hour one, so your counsel is never waiting on the facts.
