Cybersecurity Incident Response: Expert Help When an Attack Hits

From a hacked email account to a full network breach, RSecurity's incident response team helps you understand what happened, stop the damage and get your business back to normal with fast, structured cybersecurity incident response.

Why Fast Cybersecurity Incident Response Matters

When a cyber incident hits, every hour counts. Attackers use the time to move deeper into your network, steal more data or encrypt more systems. Meanwhile, rushed decisions such as wiping devices or resetting everything at once can destroy the evidence you need to understand what happened.

An experienced incident response team brings order to the chaos. We help you act in the right sequence, limit the damage, protect evidence and make clear decisions under pressure.

Not Every Attack Looks Like Ransomware

Some incidents are loud: locked files and ransom notes. Many are quiet. A compromised mailbox can send fake invoices for weeks. Stolen credentials can give an attacker silent access to your cloud services. Malware can sit unnoticed while it collects data.

Whatever the incident looks like, the goal is the same: find out how far it reached, close the attacker's access and recover safely.

Cyber Incidents We Handle

Our team responds to a wide range of security incidents affecting businesses of every size.

Business Email Compromise

Hacked mailboxes, fraudulent payment requests, hidden forwarding rules and impersonation of executives or suppliers.

Account Takeover

Stolen or misused credentials for email, cloud platforms, finance systems and other business applications.

Malware and Network Intrusions

Suspicious software, unusual network activity, unknown remote access or signs that an attacker is inside your systems.

Ransomware Attacks

Encrypted files and locked systems, handled together with our dedicated ransomware treatment service.

Data Breaches and Leaks

Stolen or exposed customer, employee or business data, and the steps needed to limit the impact.

Suspicious Activity

Something just looks wrong. We help you work out whether it is a real incident and what to do next.

Our Cybersecurity Incident Response Process

A structured approach to cybersecurity incident response that stops the damage first and finds the root cause second. These stages match those described in widely used guidance such as NIST SP 800-61, Incident Response Recommendations.

Triage

We assess what is happening, how serious it is and what needs to happen first, so you know where you stand.

Containment

We help you limit the attacker's access and stop the spread, without destroying the evidence needed for the investigation.

Investigation

We trace how the incident started, which systems and data were affected, and whether the attacker is still present.

Eradication and Recovery

We remove the attacker's foothold and help you restore clean, secure operations in a controlled order.

Lessons Learned

We report the root cause and recommend the changes that will prevent the same attack from happening again.

What to Do in the First Minutes of an Incident

While you contact our cybersecurity incident response team, these steps help protect your business and your evidence. For ransomware-specific advice, see the CISA StopRansomware guide.

  • Disconnect affected devices from the network, but leave them powered on
  • Do not delete files, emails or logs, and do not wipe any device
  • Write down what you noticed, when, and who was involved
  • Change important passwords from a device you know is clean
  • Warn staff not to act on suspicious emails or payment requests
  • Contact RSecurity before taking further recovery steps

What You Receive

Clear guidance during the incident and a clear record once it is over.

  • Hands-on guidance from first contact to recovery
  • An incident report with timeline, root cause and impact
  • A summary of every action taken
  • Recommendations to prevent a repeat attack
  • Information to support conversations with insurers or other parties
  • A debrief session with management and IT

Prepare Your Cybersecurity Incident Response Before an Attack

The best time to choose an incident response team is before you need one. You can request RSecurity to serve as your incident response team in advance, so the process, contacts and priorities are agreed before anything goes wrong.

When an incident does happen, there is no time lost finding help, explaining your systems or agreeing terms.

Who Needs Cybersecurity Incident Response?

Any organisation facing a suspected or confirmed security incident, and any business that holds customer, financial, legal or medical data and wants a plan in place. We support organisations across many sectors, including:

Cybersecurity Incident Response FAQ

What counts as a cybersecurity incident?

Any event that threatens your systems or data, such as a hacked account, malware, unauthorised access, a ransomware attack or a data leak.

What should we do while waiting for help?

Disconnect affected devices from the network but keep them powered on, do not delete or wipe anything, note what you saw and when, and change key passwords from a device you trust.

Do we have to report the incident?

It depends on your location, your sector and the data involved. We help you gather the facts, and your legal advisers should confirm any reporting obligations.

Can you act as our incident response team in advance?

Yes. You can arrange for RSecurity to serve as your incident response team before an incident, so the process and contacts are agreed ahead of time.

How is incident response different from ransomware treatment?

Incident response covers every type of security incident. Ransomware treatment is a focused service for attacks that encrypt or lock your systems, and the two work together when ransomware is involved.
