Cybersecurity firms operate in a paradox of exposure : they are paid to protect others, but are themselves the preferred targets of attackers. When a customer is hacked despite your recommendations, when a pentest damages a production system, when a SOC 2 audit is challenged by an external auditor, when your analysts have access to your customers’ most sensitive data — every job is high risk. A classic E&O is not enough; You need a specialized cybersecurity policy that explicitly includes pentest, incident response, infrastructure hosting, and customer cross-responsibility activities.

Cybersecurity company — Assur360 professional liability

IN BRIEF

Cybersecurity Company Liability

Cybersecurity firms (audits, pentests, MSSPs) need professional liability (E&O) with extended cyber coverage : if a client is hacked AFTER your mandate, you can be held liable.

Special feature: add the third-party cyber liability guarantee and the insuring agreement for failure to detect or remediate. Without it, your post-incident services can expose you to recourse.

The 6 essential protections for a cybersecurity firm

E&O cybersecurity

Erroneous recommendations, incomplete audits, pentest omitting a flaw. Limit $2 million to $10 million.

Cyber Part 1 and Part 3

Incident that affects your systems AND those of your customers (MSSP infrastructure, SOC).

Pentest Responsibility

Accidental damage to a system in production during an authorized penetration test.

Incident response

24/7 coverage for your customers’ interventions — damage during remediation.

Protection of directors

D&O — personal lawsuits against executives following an incident involving a customer.

Contractual liability

Missed SLAs, Law 25 notification obligations not met, invalidated certifications.

💡 Broker’s advice

The classic trap of cybersecurity firms: “pentest” and “cyber-incident” exclusion clauses in generic E&O policies. A general insurer can exclude damage caused during a penetration test, or refuse a claim involving a hacked customer under your supervision. Require a policy that explicitly mentions activities: pentesting, red teaming, MSSP, SOC-as-a-service, forensic, DFIR. Without it, your cover is an illusion.

Frequently Asked Questions

How much does an E&O cost for a cybersecurity firm in Quebec?

Between $2,500 and $12,000 per year for an SME with 5 to 30 employees. Firms that do active pentest, red teaming or MSSP pay more ($4,500 to $20,000). Common limits are $2 million to $5 million, amounting to $10 million for enterprise contracts.

A pentest damages a client system in production — covered?

Yes, only if your policy explicitly includes pentest activity. Generic fonts often exclude “intrusive testing allowed.” Written consent from the customer (rules of engagement) is required to avoid rejection of complaints.

A customer gets hacked despite our recommendations — responsible?

Potentially, if the customer proves that your recommendations were wrong or that you missed a detectable flaw. Your E&O covers defense and indemnification costs. Documentation (audit report, exchanges, acceptance of risk by the client) is your best protection.

We host SIEM logs at AWS for our customers — cyber coverage?

Yes, via third-party cyber infrastructure. If an incident at AWS compromises your customers through your SIEM, you are liable. Declare hosting with hyperscalers at the time of subscription. Some policies require notification within 24-48 hours of any incident.

Our customers require SOC 2 Type II or ISO 27001 — impact assurance?

Certifications often reduce the premium (10 to 30%) and are sometimes required by insurers above $5 million. A recent external pentest report or a valid SOC 2 audit is requested at renewal. Prepare a file of annual checks.

Does Bill 25 apply to us for our customers’ data?

Yes — as a cybersecurity service provider, you are a subcontractor within the meaning of Bill 25. Obligations: incident log, notifications within 72 hours, compliant contracts with your customers. Your policy must mention Bill 25 and the GDPR if you serve European customers.

Can B2B customer lawsuits reach several million?

Yes — it’s common in the industry. A hacked SME that loses 6 months of revenue can claim $2 million to $10 million. A medical or financial data breach at a large customer can generate claims of $50 million+. Tailor the E&O limit to the largest customer in your portfolio.

Are defense costs included or in addition to the limit?

Depends on the police. In “excluding defense limits”, the costs are added to the limit (preferred). In “limits including defense”, the fee reduces the limit available for compensation. Negotiate an “excluding defense limits” formula for high-risk mandates.

SOC analyst misses critical alert — covered?

Yes, via the SOC/MSSP operating E&O. Covers omissions, triage errors, customer notification delays. Recommended high limits ($5M+) for 24/7 SOCs. Policies often require evidence of ongoing analyst training and documented procedures.
