Security
Incident Response Management Services
Prepare your organization to handle security incidents with clear roles, tested playbooks and the evidence you need, and get hands-on support to contain and recover.
When an Incident Happens, Preparation Decides the Outcome
The first hours of a security incident are chaotic. Who decides whether to shut down a system? Are the right logs available, and how far back do they go? When must customers, regulators or insurers be notified? Who speaks to the press? Organizations that answer these questions for the first time during a ransomware attack or data breach lose valuable time, destroy evidence by accident and often extend the outage far beyond what was necessary.
Hanoi Technology helps you prepare before it happens and respond when it does. We develop incident response plans and scenario playbooks aligned with NIST SP 800-61 Revision 3 and the NIST Cybersecurity Framework 2.0, improve logging and forensic readiness, rehearse decisions in tabletop exercises and support your team with investigation, containment, eradication and recovery, followed by a lessons-learned review that strengthens defenses.
The Challenge
Why Incident Response Breaks Down
Weak response is usually the result of gaps that could have been closed in advance.
Plans That Exist Only on Paper
An incident response document was written for an audit but never tested, and key contacts, systems and responsibilities are out of date.
Insufficient Logs and Evidence
Logs are not retained long enough or not collected at all, making it impossible to determine how attackers got in or what they accessed.
Unclear Decision Authority
Technical teams wait for approval to isolate systems while executives lack the information needed to decide, and attackers keep moving.
Recovery Without Root Cause
Systems are restored from backup without removing the attacker’s access, leading to reinfection within days.
Business Value
Benefits of Prepared Incident Response
Faster Containment
Predefined playbooks and authority to act let teams isolate affected systems and accounts quickly.
Reduced Business Impact
Coordinated response limits downtime, data loss and recovery cost.
Preserved Evidence
Forensic readiness ensures logs and artifacts are available for investigation, insurers and legal counsel.
Confident Communication
Templates and clear responsibilities support timely, accurate updates to staff, customers, partners and regulators.
Regulatory Readiness
Documented procedures help meet notification timelines under regulations such as GDPR and sector-specific rules.
Continuous Learning
Post-incident reviews turn each event into concrete improvements in prevention and detection.
Incident Response Is Part of Risk Management
NIST SP 800-61 Revision 3 frames incident response as part of overall cybersecurity risk management, connected to governance, protection, detection and recovery rather than an isolated technical process. We help you build response capability that is embedded in how your organization manages risk.

Use Cases
Incident Response Scenarios
Examples of incidents our playbooks and support address.
Ransomware Attack
An organization detects encryption on file servers and follows its playbook to isolate systems, assess backup integrity and plan recovery.
Business Email Compromise
A finance employee’s mailbox is compromised and used to request fraudulent payments; the team revokes sessions, removes malicious rules and alerts partners.
Cloud Account Compromise
Exposed access keys are used to create resources in a cloud account; responders rotate credentials, remove resources and review audit logs.
Data Exposure in an Application
A misconfigured API exposes customer records; the team closes access, determines affected users and prepares notifications.
Insider Data Theft
A departing employee downloads sensitive files; investigators reconstruct activity and support HR and legal processes.
Third-Party Breach
A software supplier reports a compromise; the organization assesses exposure, rotates credentials and reviews integrations.

Incident Response FAQ
What should an incident response plan include?
A good plan defines what counts as an incident, severity levels, roles and responsibilities, decision authority, escalation paths, contact details for internal teams and external parties such as legal counsel and insurers, communication procedures, evidence handling and regulatory notification requirements. It is supported by scenario playbooks with concrete steps for common incidents like ransomware, account compromise and data exposure. Plans should be reviewed at least annually and after significant changes.
Can you help us during an active incident?
Yes. We can support triage, scoping, log and endpoint analysis, containment, eradication and recovery, working alongside your IT and security teams. Response capacity and response times are agreed in advance as part of a support arrangement, so we recommend setting this up before an incident occurs. If you are facing an incident now, contact us and we will tell you honestly what support we can provide and how quickly.
What is a tabletop exercise and who should take part?
A tabletop exercise is a facilitated discussion in which participants walk through a realistic incident scenario and make decisions as it unfolds. Technical exercises test detection, containment and recovery steps, while executive exercises focus on business decisions, communication and legal considerations. Participants typically include IT, security, legal, communications, management and key business owners. Exercises reveal gaps in plans and build confidence before a real event.
How do you preserve evidence during an incident?
We prioritize collecting volatile data and logs before systems are changed, use forensic tools that record what was collected and when, maintain a chain of custody and store evidence securely. Containment actions are chosen to stop the attacker while keeping evidence intact where possible. This matters for understanding the incident, for insurance claims and for any legal or regulatory follow-up.
How do we know when we must notify regulators or customers?
Notification obligations depend on your jurisdictions, industry and the type of data involved. For example, GDPR generally requires notifying the supervisory authority within 72 hours of becoming aware of a qualifying personal data breach. We help build notification criteria and templates into your plan and provide technical facts during an incident, while final legal decisions should be made with your legal counsel.
How is incident response readiness work priced?
Readiness assessments, plan development and tabletop exercises are typically fixed-scope projects, priced by the size of the organization, number of scenarios and participants. Ongoing response support is usually arranged as a retainer or managed service with agreed hours and response times. We provide a clear proposal after an initial conversation about your environment, existing capabilities and requirements.
