Emergency cyber security
questions answered
Q.What should I do if my business is under a cyber attack right now?
Immediately: (1) Call Coreitech on 0203 834 9728 — our security engineers respond within 15 minutes 24/7; (2) Do NOT turn off affected machines — this destroys forensic evidence; (3) If ransomware is actively encrypting files, physically disconnect affected devices from the network immediately (unplug ethernet, disable Wi-Fi); (4) Do not pay the ransom before speaking to us — around 30% of businesses that pay never get their data back; (5) Preserve all evidence — screenshot ransom notes, don't delete suspicious emails.
Q.What is emergency cyber security support?
Emergency cyber security support is immediate, unplanned incident response for businesses experiencing an active cyber attack or security breach. Coreitech's emergency response service provides a senior security engineer within 15 minutes of contact — available 24/7, 365 days a year. We handle ransomware, business email compromise, data breaches, account takeovers, network intrusions, and any other active security incident.
Q.How quickly can Coreitech respond to a cyber incident?
Our target response time for emergency cyber security incidents is 15 minutes — that's time to a live senior engineer, not an automated acknowledgment. For active ransomware or confirmed breaches, we also have on-site emergency response available in Central London typically within 1–2 hours.
Q.Do I need to pay the ransomware ransom?
No — not without exhausting all other options first. Approximately 30% of UK businesses that pay a ransomware ransom never receive a working decryption key. Payment funds criminal operations and marks you as a target for repeat attacks. Coreitech will investigate backup viability, explore decryption options, and advise on the full range of recovery options before any payment decision is made.
Q.What is the GDPR notification requirement for a data breach?
Under UK GDPR, if a cyber incident results in a breach of personal data that risks the rights and freedoms of individuals, you must report it to the ICO within 72 hours of becoming aware of it. Failure to notify, or being found to have inadequate security controls, can result in significant ICO fines. Coreitech helps you assess whether notification is required, prepares the ICO submission, and documents your response for regulatory purposes.
Q.Do you provide on-site emergency cyber security support in London?
Yes. For active incidents where remote response is insufficient — particularly ransomware with network-wide encryption, physical infrastructure compromise, or complex forensic investigation — Coreitech provides on-site emergency response in London. Most Central London, City, Canary Wharf, and Southwark businesses can be reached within 1–2 hours of initial contact.
Q.What happens after the emergency incident is contained?
After containment and recovery, Coreitech produces a full written incident report: root cause analysis (how did the attacker get in?), forensic timeline of the attack, scope of compromise (what data was accessed or encrypted?), remediation steps completed, and recommended hardening to prevent recurrence. We also assist with cyber insurance claim documentation and any regulatory notification requirements.
Under attack right now?
Don't wait. Every minute matters in a cyber incident. Our engineers respond in 15 minutes, 24/7.
