The first hours of an incident decide its cost

Unclear ownership, lost logs and rushed clean-up turn a contained incident into a business crisis — and destroy the evidence you need for insurers, regulators and courts.

Ransomware & extortion

Encrypted systems, stolen data and a ticking clock — you need containment, scoping and recovery decisions fast.

Business email compromise

Hijacked mailboxes and fake payment instructions cause direct financial loss and need a forensic trail.

Data breaches

Personal data exposure triggers CERT-In reporting within 6 hours and obligations under the DPDP Act, 2023.

Insider threats & fraud

Data theft, IP theft and employee misconduct demand discreet, legally sound investigation.

Our DFIR services

Readiness, response and investigation — delivered by one team that understands both the technology and the law.

Why an Incident Response Retainer?

Organisations with an agreed responder recover faster, because contracts, contacts, access and evidence procedures are sorted before the incident — not during it.

Faster response

Pre-agreed response times and an escalation path you can call at any hour.

No procurement delay

Terms, NDAs and scope are already signed, so work can start immediately.

Readiness built in

Onboarding review of your logging, backups and IR plan closes gaps before an attacker finds them.

One trusted team

The same responders learn your environment, people and priorities over time.
