9 Steps Every Business Needs to Know About Compliance After a Cyber Attack - Wyrdex
A cyber attack is not just a technical problem it’s also a legal and regulatory issue.
Once your systems are breached, following the rules becomes critical. Executives, regulators, insurance companies, and customers will all want answers. Fast.
Are you prepared to meet those expectations?

If not, this guide is for you.

We’ll show you how to manage compliance after a cyber attack, reduce your legal risks, and rebuild trust. We’ll also explain how Wyrdex can support you through every step quickly and accurately.

What Does It Really Mean to Be “Compliant After a Cyber Attack”?

Compliance after a breach means following all applicable laws, regulations, and contractual obligations. This includes:
Reporting the incident within a mandated time frame

  • Notifying customers and partners
  • Documenting everything that was impacted
  • Taking immediate corrective actions
  • Cooperating with investigators and regulators

Requirements vary by industry, location, and data type.

  • GDPR applies if you store or process personal data in Europe
  • NIS-2 applies if you operate in critical infrastructure
  • PCI DSS applies if you handle cardholder data

Step 1: Quickly Notify the Appropriate Authorities

Speed is everything. If you discover a data breach, GDPR requires notification within 72 hours.

Other frameworks have similar deadlines.

  • National Data Protection Authorities (e.g., Norway’s Datatilsynet)
  • Sector-specific regulators
  • Law enforcement (especially in cases of extortion or national security threats)

Penalties increase with delays or vague disclosures. Be transparent. Stick to the facts. Report what happened, when, what data was compromised, and how you’re responding.

Wyrdex helps you draft and submit compliant reports on time, ensuring adherence to local and industry-specific regulations.

Step 2: Notify Affected Individuals Promptly

If customer data was compromised, you are legally required to inform those affected.
This is mandated by GDPR, HIPAA, and other data protection laws.
Your message should be clear and actionable. It must include:

  • What happened
  • What data was exposed
  • Potential risks to the individual
  • Recommended actions they should take
  • What you’re doing to protect them

Do not delay or sugarcoat the message. The longer you wait, the more trust you lose.
Wyrdex helps you craft legally sound, clear notifications to maintain transparency and compliance.

Step 3: Maintain Records and Preserve Evidence

Regulators may investigate your business after a cyber attack.
Be prepared.
Document every step of your response:

  • Timeline of events
  • Forensic investigation findings
  • Security logs
  • Internal communications
  • Third-party reports
  • Legal counsel input

Preserve this evidence.
It will support legal defenses, insurance claims, and demonstrate compliance.
Wyrdex simplifies this process with incident report templates and digital evidence management.

Step 4: Review and Update Your Policies

Your existing cybersecurity policies will be scrutinized.
Outdated or missing procedures can lead to non-compliance.
Review these critical documents:

  • Incident Response Plan
  • Data Breach Notification Policy
  • Access Control Policy
  • Backup and Recovery Plan
  • Vendor Risk Management Policy

Update them based on the lessons learned from the attack.
Wyrdex audits and revises post-incident policies to align with the latest cybersecurity and data protection standards.

Step 5: Cooperate with Investigators and Auditors

Regulators or law enforcement may launch an investigation.
Full cooperation is essential.
Provide appropriate logs, documentation, and access to team members. Respond professionally and factually.
Avoid speculation or defensiveness.
If you have a Managed Security Service Provider (MSSP) like Wyrdex, we handle the technical side and assist throughout the investigation.

Step 6: Perform a Root Cause Analysis (RCA) and Share It

Most compliance frameworks require a Root Cause Analysis (RCA).
This is your opportunity to demonstrate transparency and a commitment to improvement.
Identify:

  • How the attacker gained access
  • Which systems or processes failed
  • What you’ve done to resolve it
  • What new controls you’re implementing

An RCA proves you’re not just reacting you’re evolving.
Wyrdex delivers forensic-backed RCA reports supported by endpoint logs and threat intelligence.

Step 7: Strengthen Controls and Document Remediation

Regulators want proof that the breach won’t happen again.
Demonstrate:

  • Upgraded firewalls, endpoint protection, or detection systems
  • Implementation of multi-factor authentication (MFA)
  • Patched systems and resolved vulnerabilities
  • Improved monitoring and alerting
  • Regular employee cybersecurity training

If you lacked proper logging or detection before the attack, fix that immediately.
Wyrdex offers infrastructure hardening, Managed Detection and Response (MDR), and continuous compliance monitoring.

Step 8: Validate Your Defenses with Testing

Compliance doesn’t end with remediation. You must prove your defenses are effective.
This requires penetration testing and cyber resilience audits.
Regular testing should include:

  • Web application penetration testing
  • Internal and external vulnerability scans
  • Tabletop incident response exercises
  • Disaster recovery simulations

Wyrdex conducts third-party testing and certification to validate your progress and compliance posture.

Step 9: Engage with Cyber Insurance Providers

If you carry cyber insurance, you must present a clear claim with evidence of compliance.
Insurers may require:
Regular testing should include:

  • An incident response plan
  • Proof of encryption and MFA
  • Backup verification
  • Evidence of reasonable protective measures

Failure to meet requirements may result in denied claims.
Wyrdex helps clients create insurance-compliant incident response plans before and after breaches.

Why Businesses Struggle with Compliance After a Breach

The biggest challenge is lack of preparation.
Many companies are unaware of their regulatory obligations until it’s too late. Others have outdated policies or no formal IT structure. Some never trained employees on basic security protocols.
This leaves them vulnerable not just to hackers, but to regulators, courts, and customers.
It’s not just about defending against cybercrime it’s about proving due diligence.
Wyrdex helps you build that foundation before an attack and safeguard it after one.
