When Every Minute Counts
Without experienced responders, a breach compounds by the hour. Attackers dwell in your environment for days or weeks before detection. The decisions you make in the first 24 hours determine whether you recover in days — or spend six months rebuilding.
Binary Response operates 24/7 with practitioners who have resolved 100+ incidents across ransomware, BEC, APT intrusions, and data breaches. You speak to senior DFIR professionals from the first call — not a triage queue.
What We Handle
- Ransomware — containment, scoping, recovery, and negotiation advisory
- Business Email Compromise (BEC) — investigation, account lockdown, and financial recovery guidance
- Advanced Persistent Threat (APT) — detection, eradication, and dwell-time analysis
- Insider threat — covert investigation, evidence preservation, HR and legal liaison
- Cloud incidents — M365, Azure, AWS, Google Workspace
- Data breach scoping — identify what was accessed, by whom, and when
- DDoS and extortion — crisis management and recovery
Our Methodology
Built on NIST SP 800-61 and SANS PICERL frameworks. Every engagement produces a documented, defensible chain of evidence that stands up to ICO, FCA, and courtroom scrutiny.
Deliverables
- Executive incident summary your board can act on immediately
- Technical forensic report with timeline, indicators of compromise (IoCs), and root cause
- Evidence package that satisfies insurers, regulators, and legal proceedings
- Remediation and hardening recommendations to prevent repeat attacks
- Regulatory notification support (ICO, PRA, FCA where applicable)
Frequently Asked Questions
How quickly can you respond?
Retainer clients reach a senior practitioner within 1–4 hours depending on tier. Ad-hoc clients are typically engaged within a few hours of first contact. Out-of-hours response is included — attackers don't respect business hours.
Do you work remotely or on-site?
Both. Most containment and investigation work starts remotely — it is faster and sufficient for most incidents. On-site deployment is available when you need physical access to systems or a visible presence for stakeholder confidence.
Can you work alongside our existing IT team?
Yes — and we regularly do. We establish clear lanes of work immediately so your team and ours aren't duplicating effort. We brief your team at each stage and hand back cleanly at the end.
What information do you need to get started?
A brief description of what you're seeing, contact details for your technical and business leads, and access to whatever logging or telemetry you have. We can work with limited visibility and build from there.
Will you handle communications with our insurer?
Yes. We work directly with major UK cyber insurers and know their documentation requirements. We brief your broker and provide the evidence package they need to process the claim without delay.
