Respond with clarity when
a security incident happens
Incident response is the structured work of establishing what happened, limiting the damage, investigating the evidence that exists and returning the business to a controlled state.
A cybersecurity incident rarely stays in one place. Suspicious activity can surface on endpoints, in identities and privileged accounts, inside applications, across the network, in cloud environments and in the business data those systems hold.
Cylentrix combines cyber incident response with digital forensics across all of them: endpoint forensics, network forensics, cloud forensics, identity and email investigation. Detection tooling raises the signal; incident response decides what it means and what happens next.
What an investigation produces
- Collected evidence, aggregated and correlated across the in-scope sources
- A reconstructed timeline showing the sequence of relevant activity
- Indicators associated with the incident, recorded for detection and blocking
- An impact assessment covering affected assets and potential business exposure
- Written findings with prioritised recommendations for response and recovery
What the engagement covers
-
Incident triage
Assess reported security events and help determine their potential severity, scope and priority.
-
Incident containment
Support actions designed to limit the impact of an incident and prevent it spreading further.
-
Threat investigation
Analyse available security information to understand suspicious activity and how it progressed.
-
Digital forensics
Examine relevant digital evidence to help establish what happened, where and when.
-
Malware & artifact analysis
Review relevant files, system artifacts or indicators associated with an incident where applicable.
-
Root cause analysis
Identify contributing factors and the weaknesses that allowed the incident to occur.
-
Recovery support
Support the transition from containment and investigation toward controlled service recovery.
-
Post-incident review
Document findings and identify improvements to security controls and response processes.
From detection
to recovery
Cylentrix follows a defined incident response lifecycle. Each stage has an owner, an objective and a decision point, so an engagement never depends on improvisation under pressure. Evidence is identified, preserved, collected, analysed, correlated and documented as the work proceeds.
-

Scope, timing and containment actions are agreed with your team at every stage
Evidence handling procedures should be aligned with applicable organisational, regulatory and legal requirements. Where an incident may lead to legal, regulatory or insurance proceedings, we recommend involving your legal counsel and, where required, appropriately qualified specialists early in the engagement.
Understand what happened,
and reduce the impact
An investigation answers a fixed set of questions: what happened, when it started, what was affected, how the activity progressed, what was at risk, what enabled it, and what should change.
-
Timeline reconstruction
One agreed sequence of events, so leadership and technical teams work from the same account of the incident.
-
Impact assessment
A defined view of which systems, accounts and data were affected, supporting reporting and notification decisions.
-
Root cause analysis
The contributing factors behind the incident, so remediation addresses the cause rather than the symptom.
-
Security improvement
Prioritised recommendations that reduce the likelihood and cost of the next incident.
The goal is not only to close the immediate incident. Post-incident analysis exists so the same weakness is harder to exploit next time, and so the organisation responds faster and more confidently when the next security event arrives.
Incident readiness for
regulated industries
Every sector answers a different question first after an incident: what stopped, what was exposed, and what has to be reported. Cylentrix investigates with those obligations in view.
-
BFSI
Payment platforms and core banking records mean incidents must be contained, investigated and documented for regulators.
-
Healthcare
Clinical systems cannot simply be switched off, so containment protects patient care while evidence is preserved.
-
Manufacturing
Plant IT, OT links and supplier connections need containment sequenced so production is not halted further.
-
IT & Technology
Multi-tenant platforms, source control and cloud workloads scatter evidence across many environments at once.
-
Government
Citizen-facing services and inter-department systems call for disciplined investigation and clear reporting.
-
Retail
Store systems, e-commerce and payment flows need quick containment and clear findings before peak trading.
-
Education
Open campus networks and research data raise hard questions of scope, access and exposure to answer.
-
Logistics & Critical Infrastructure
Tracking, scheduling and control systems need recovery sequenced so evidence is not lost on the way back.
Why enterprises choose Cylentrix for
incident response & forensics
An incident touches security tooling, IT infrastructure and connectivity at the same time. Cylentrix works across all three, so investigation is not held up waiting for a handover.
Cybersecurity, IT and telecom expertise
Incidents cross security platforms, server and cloud estates and the network underneath. One partner covers all three.
Structured incident response
A defined lifecycle from preparation and detection through containment, investigation, eradication, recovery and review.
Security investigation capability
Analysts who work through security data methodically to establish what actually happened, not what is assumed.
Digital forensics
Examination of endpoint, network, cloud, identity, email and file evidence relevant to the incident under investigation.
Enterprise environment understanding
Containment decisions are made with production realities in mind, because we run enterprise estates every day.
Cross-domain investigation
Evidence from different environments is examined together, so activity is not misread in isolation.
Evidence-focused analysis
Findings are tied to the artifacts they came from and documented as the investigation progresses.
Recovery and post-incident improvement
Engineers who help restore affected systems, then turn the findings into stronger controls and a better response plan.

Incident response and forensics,
answered directly
The questions security and IT leaders ask before, during and after a cybersecurity incident, answered the way our responders answer them.
What is incident response?
Incident response is the structured process an organisation follows when a cybersecurity incident is suspected or confirmed. It covers preparation, detection and validation, containment, investigation, eradication of identified causes, recovery of affected systems, and a post-incident review. The purpose is to limit impact, establish what happened and return the business to a controlled state.
What is digital forensics?
Digital forensics is the examination of digital evidence to establish what occurred on a system, account or network. In a cyber incident it typically covers endpoint artifacts, network activity records, cloud and identity logs, email artifacts and files. Findings are documented alongside the evidence they came from, so the investigation can be explained and reviewed later.
When should an organisation initiate an incident response investigation?
As soon as activity is observed that cannot be explained by normal operations: unexpected administrative or privileged access, suspected malware, unusual data movement, alerts from security tooling that cannot be closed as benign, systems behaving abnormally, or a credible report from a user, customer or third party. Starting early usually means more evidence is still available.
What types of cybersecurity incidents can incident response teams investigate?
Common categories include malware and ransomware activity, business email compromise and phishing, account and credential misuse, unauthorised access to systems or cloud resources, suspected data exposure, insider activity, and web or application-layer compromise. The investigative approach stays the same; the evidence sources change with the incident type.
What is the difference between incident response and digital forensics?
Incident response is the overall process of managing an incident, including containment, recovery and communication. Digital forensics is the investigative discipline within it that examines evidence in detail to establish facts. Incident response answers what should we do now; digital forensics answers what exactly happened and how.
What types of evidence can be investigated during a cyber incident?
Typically endpoint artifacts and process activity, security and system logs, network traffic records and connection history, cloud control-plane and audit logs, authentication and access records, email headers and message artifacts, and relevant files with their metadata. What is actually available depends on the environment, the tooling in place and how long the logs are retained.
How does incident response help reduce the impact of a cybersecurity incident?
By replacing improvisation with sequence. Containment limits further spread while the investigation establishes scope, so recovery is based on evidence rather than guesswork and restored systems are less likely to reintroduce the problem. The post-incident review then closes the contributing weaknesses, which reduces the likelihood of a repeat.
How can Cylentrix help with incident response and forensics?
Cylentrix supports incident response planning and readiness before an incident, and triage, containment support, threat investigation, digital forensics, root cause analysis, recovery support and post-incident review during and after one. Because we also deliver managed IT and network services, investigation and recovery can proceed across security, infrastructure and connectivity without waiting on a handover between vendors.
