Cyber insurers view Cloudflare as a demonstrable security control. Irish SMEs using Cloudflare can expect lower premiums and better coverage terms. Here is how.

When a Donegal hospitality group renewed its cyber insurance policy in late 2025, its broker asked a set of specific technical questions during the underwriting process: Did the business use a web application firewall? Did it have DDoS protection? Were SSL certificates current and correctly configured? Could it provide audit logs in the event of an incident? The group had implemented Cloudflare across all its websites the previous year, primarily to improve site performance and block fake bookings. When the underwriter reviewed the answers, the group was moved into a lower risk category. Its renewal premium came in 20 percent below the previous year's, despite the general market trend of rising cyber insurance costs.

Cyber insurance is no longer optional for most Irish businesses of any meaningful size. Clients require it, lenders expect it, and the financial exposure of a serious breach — business interruption, forensic investigation, regulatory notification, legal liability, reputational recovery — exceeds what most SMEs could absorb without insurance. The challenge is that premiums have increased significantly as insurers have accumulated better data on the actual cost and frequency of cyber incidents. Businesses that cannot demonstrate specific security controls are being quoted higher premiums, subjected to more restrictive coverage terms, or — in some cases — declined entirely.

WHAT: How Cyber Insurance Underwriting Has Changed

Two years ago, cyber insurance underwriting for a small Irish SME was relatively straightforward: basic questions about turnover, sector, and whether the business had antivirus. Today, underwriters ask detailed technical questions and increasingly require evidence rather than self-reported answers. They want to see MFA enabled, patch management processes documented, backups tested, and — particularly for businesses with customer-facing websites — web application firewalls and DDoS protection in place.

NCSC Ireland has published guidance on the security baseline that cyber insurers increasingly expect, noting that basic perimeter controls like web application firewalls are now considered standard requirements rather than advanced measures.[^1] Cloudflare's free plan addresses several of the controls that underwriters most commonly ask about: DDoS protection, WAF rules, SSL certificate management, and audit logging. This is why insurers increasingly recognise it as a meaningful risk reduction measure.

The underwriting logic is straightforward. A business with no web application firewall is exposed to a wide range of automated attacks against its customer-facing systems. A business with Cloudflare's WAF active has automated protection against the most common attack categories. The probability of a claim is lower. The premium reflects that.

WHAT NOW: What Cloudflare Provides That Insurers Actually Check

DDoS protection is the most visible. A Distributed Denial of Service attack — flooding your website with fake traffic until it goes offline — is one of the most common threats to businesses with customer-facing booking or e-commerce systems. Cloudflare's global network absorbs DDoS traffic automatically, keeping your site online even under significant attack volumes. Underwriters view this as a direct reduction in business interruption risk: a site that stays online during an attack does not generate a claim.

The web application firewall filters requests to your site and blocks known attack patterns — SQL injection, cross-site scripting, credential stuffing. Cloudflare's free WAF includes rules maintained by Cloudflare's threat intelligence team, updated continuously as new attack patterns emerge. An Garda Síochána's National Cyber Crime Bureau notes that automated web attacks account for a significant proportion of the incidents reported by Irish businesses.[^2]

SSL certificate management matters both for security and for insurance. An expired or misconfigured SSL certificate on a business website handling customer data can itself constitute a data protection breach under GDPR. Cloudflare's automatic certificate provisioning and renewal eliminates this risk entirely. The Data Protection Commission expects businesses handling personal data to maintain current encryption for data in transit — Cloudflare's SSL addresses this baseline requirement.[^3]

Audit logs are increasingly requested in insurance underwriting and are essential in the event of a claim. Cloudflare logs all requests to your site, including blocked attacks, suspicious traffic, and access patterns. If you need to demonstrate to an insurer, an investigator, or a regulator what happened on your site during an incident, Cloudflare's logs provide the evidence base.

WHY IT MATTERS: The Premium Reduction Calculation

The financial logic is clear. Cloudflare's free plan costs nothing. The Pro plan costs €20 per month, or €240 per year. If implementing Cloudflare — and documenting it as a security control for your insurer — reduces your annual premium by 15 to 25 percent, the payback for a typical SME is immediate. A business paying €4,000 per year for cyber insurance that achieves a 20 percent reduction saves €800 per year. The Pro plan investment of €240 delivers a net saving of €560 per year, with the additional security benefit.

Beyond premiums, the quality of coverage matters. Insurers are increasingly adding exclusions for incidents that could have been prevented by standard controls. A claim arising from a DDoS attack on a business that had no DDoS protection may face a coverage challenge. A claim from a business that had Cloudflare active and properly configured is more defensible — the business took reasonable precautions, and the incident was not the result of obvious negligence.

Cyber insurance is not a substitute for security controls. But having the right controls in place changes the terms on which you can buy insurance — and whether it pays out when you need it.

WHAT NEXT: Three Actions to Reduce Your Insurance Exposure

Activate Cloudflare on your business website before your next renewal. If you do not have Cloudflare, sign up for the free plan this week. If you already have it, log into your dashboard and confirm that DDoS protection, WAF rules, and SSL are all active.
Before your next renewal conversation with your broker, compile a one-page summary of your security controls: Cloudflare (specifying DDoS, WAF, SSL), MFA status, backup arrangement, and whether you have an incident response plan. Present this proactively rather than waiting to be asked. Brokers can advocate more effectively for better terms when they have evidence to support the application.
Review your current policy for exclusions. Look specifically for clauses that exclude coverage when "reasonable security measures" were not in place. If your policy contains such a clause, ask your broker to confirm that your current controls — including Cloudflare — meet the insurer's definition of reasonable.
