Cyber Defense · Incident Management
Most security stops at the breach. We don’t.
Containment tells you the attack is over. It doesn’t tell you who got in, how, or whether they’re still there. We close the incident and answer the question the board asks next: who did this?

Active incident?
Every minute of dwell time widens the blast radius.
Don’t wipe or reimage affected systems — preserve the evidence. Reach us now and we triage within hours, with critical findings escalated inside one hour.
How it fits together
One discipline, three capabilities
Incident management is a single lifecycle, not three separate purchases. We contain the threat, then reconstruct the full chain back to the people behind it.
Branch 01
Incident Response
Rapid, structured breach response to contain threats, remove attacker presence, and restore operations under pressure.
Standard · NIST SP 800-61
Outcomes
- 01Threat contained, attacker presence removed
- 02Operations restored on a documented timeline
- 03Containment & eradication actions logged
- 04Recurrence path closed and verified
Branch 02
Digital Forensics
Forensic-grade investigation that establishes what happened, how it happened, and the full impact across affected systems.
Standard · ISO/IEC 17025
Outcomes
- 01Evidence integrity preserved and verifiable
- 02Timeline reconstructed, cited to source logs
- 03Affected assets and exfiltrated data mapped
- 04Documentation ready for regulators
Branch 03
Cybercrime Investigation
Forensically sound investigation to uncover the perpetrator, preserve evidence for legal action, and determine intent.
Standard · MITRE ATT&CK · Diamond Model
Outcomes
- 01Perpetrator identified with evidence
- 02Insider versus external determined
- 03Evidence preserved for legal action
- 04Regulatory compliance maintained
The attribution method
We find the attacker, not just the breach
Where most providers close the ticket at containment, we reconstruct the full chain and name the entry point — Patient Zero, the vector, and insider versus external.
Triangulate
When historical logs are missing, we corroborate technical artifacts against physical access, HR, and remote-access records to rebuild user activity.
Human intelligence
Structured, non-accusatory interviews with staff and suspects surface anomalies tooling misses — suspicious email, unusual access, policy gaps.
Behavioural verification
Where warranted, a certified examiner administers polygraph as a supplementary lead. In Indonesia it is admissible under KUHAP — but no finding rests on it alone.
Synthesis & attribution
Testimony is correlated with recovered artifacts to finalise the entry point and the specific vulnerability — technical or human — that was exploited.
Polygraph results function strictly as investigative leads, corroborated against logs before any enter the root-cause analysis.
Before the incident does
Let's talk before you need us
A retained-response agreement puts the team, scope boundaries, and escalation path in place now — so when minutes matter, no one is negotiating an SOW.
End to end
The engagement lifecycle
Every engagement moves through the same five stages. Each gate calibrates the next — scope follows evidence, not assumption.
Respond & Contain
Stop the bleeding, preserve evidence.
Investigate & Attribute
Patient Zero, vector, perpetrator.
Validate
Independently confirm findings hold.
Recover & Harden
Close gaps with named ownership.
Assure
Equip customers, regulators, board.
What an engagement delivers · coordinated work streams
Assessment & Review
Independent validation of the incident-response work — scope, evidence quality, root cause — with a confidence level per finding.
vCISO — embedded leadership
Standing security leadership for the executive team during the highest-pressure window, on call for customer and regulator engagement.
Customer Assurance + Breach Notification
A single incident narrative crafted for banking customers, regulators, and the board — attestation letters, FAQs, questionnaire responses.
Control Hardening
Structured remediation across identity, logging, segmentation, and endpoints — each action with named ownership and evidence of closure.
What you receive
A report a court will accept
The deliverable is built the way our real investigations are written — a forensic timeline mapped to host ownership, personnel attribution correlated to the evidence, a full root-cause analysis, and a strategic roadmap where every recommendation carries an owner and a date.
Structure abstracted from delivered investigations. All client detail withheld.
Executive summary
The incident in board language — what happened, the confirmed attacker, and the decisions required. Confidence stated per finding.
Investigation methodology
How the evidence was collected and correlated, with the forensic timeline carried forward from first response.
Forensic timeline & host attribution
The confirmed attacker timeline mapped to host ownership — Patient Zero, dwell time, and the vulnerabilities exploited, cited to source logs.
Personnel examination & interviews
Structured HUMINT findings correlated to the technical timeline — a forensic correlation, never an accusation.
Comprehensive root-cause analysis
The full chain reconstructed to the entry point — technical or human — with SHA-256 integrity and chain-of-handling throughout.
Key findings & conclusion
The confirmed determination: insider versus external, actor named where the evidence supports it, nothing where it doesn't.
Strategic roadmap
Prioritized recommendations, each with a named owner and a target date, so closure is measurable — not aspirational.
Where we focus
Built for the incidents that carry consequences
Banking and energy are where we concentrate — but the method is sector-agnostic. The same lifecycle, attribution capability, and evidence standards apply wherever an incident has consequences.
Built for banking & finance
Indonesian and regional institutions answer to OJK, Bank Indonesia, and MAS TRM — and to banking partners who freeze access until remediation is proven. We deliver regulatory breach notification input, customer-assurance attestation, and a pre-authored questionnaire response library (CAIQ, SIG).
Built for energy & critical infrastructure
In energy, manufacturing, and public infrastructure an incident can force an unsafe shutdown. We run OT- and SCADA-aware investigation across IT and OT (NIST, ISA/IEC 62443), reconstruct the kill chain from IT into control systems, and weigh containment against process safety — never applied blindly.

FAQ
Common questions
Straight answers. If yours isn't here, ask us directly.
Contact us immediately via the incident line and, if you can, preserve evidence: do not wipe or reimage affected systems, and keep logs. We triage scope, severity, and blast radius within hours, with critical findings escalated to you inside one hour. A retained-response option puts the SLA in place before you need it.
Build the program
Pairs well with
vCISO — Virtual CISO
The hardest work starts after the incident closes. Add a vCISO to own the remediation roadmap, the regulator correspondence, and the maturity climb that follows — the exact arc we ran for Intikom.
Corporate Investigations
When the forensics point inward. We establish what moved; the investigations team establishes who moved it, to a standard HR and counsel can act on.
Malware Removal & Ransomware Recovery
The restoration half. While IR runs the investigation, the recovery team eradicates persistence and rebuilds clean — so you get answers and a working business.
