Hiscox’s warning matters because ransomware is rarely a one-off event
A report carried by SecurityBrief Asia says that Hiscox has warned that ransomware can hit UK small and medium-sized enterprises more than once. That point deserves attention well beyond the immediate drama of a ransomware incident. For an SME, the first attack can create a damaging combination of operational downtime, emergency IT spend, customer anxiety and management distraction. A second incident can be more severe because the business may already have depleted cash reserves, lost confidence in a supplier or hurried through a partial recovery.
The key lesson is not simply that cyber criminals are persistent. It is that an organisation that restores its systems without properly identifying the initial route of entry may remain a viable target. Restoring a backup gets files and services working again; it does not automatically remove stolen credentials, insecure remote access, unpatched software, malicious persistence tools or weak supplier connections.
For UK SMEs considering cyber insurance, this changes the question from “Will a policy pay after an attack?” to “Will the business be able to contain, investigate and recover from an attack without becoming vulnerable again?” A useful policy is one component of resilience, not a substitute for it.
Why a business may suffer repeat ransomware attacks
Attackers can retain access after the first disruption
Modern ransomware incidents often involve more than file encryption. Criminal groups may steal data before encrypting systems, monitor a network for days or weeks, and use legitimate administrator accounts to move around it. If a business rebuilds only the visibly affected device or server, an attacker may still have a route back into the environment.
This is particularly relevant for SMEs using a mixture of cloud applications, remote desktop access, outsourced IT support and older on-premises systems. Responsibility can be fragmented: the managed service provider manages endpoints, a software vendor manages an application, and the business itself manages user access. Gaps between those responsibilities are attractive to attackers.
A ransom payment does not provide closure
Paying a ransom, where lawful and considered, may appear to offer the fastest route back to operations. But it does not guarantee a functioning decryption tool, deletion of stolen data, or the end of criminal interest. It can also leave the underlying security weaknesses untouched.
UK businesses should take specialist legal and incident-response advice before taking any action involving payment. Sanctions rules and the identity of the recipient can create serious legal considerations. More fundamentally, a payment decision should never replace forensic investigation and a structured remediation programme.
Public knowledge of disruption can attract further pressure
An incident may become known to customers, competitors, suppliers or other criminal groups through leaked data, public claims by ransomware gangs, or an obvious service outage. That visibility can increase the risk of follow-on phishing, business email compromise and fraud attempts aimed at finance teams or customers.
For example, a criminal may impersonate a supplier during the confusion after an incident and send revised bank details. The ransomware event may be contained, while the financial fraud risk has only started.
The cyber insurance implications for UK SMEs
Cyber insurance can help fund and coordinate specialist assistance at the point when an SME is least able to source it quickly. Depending on the wording, a policy may cover incident-response professionals, digital forensics, legal advice, customer notification, public relations support, data restoration, business interruption and certain cyber extortion costs.
However, SME owners should avoid assuming that every cyber policy responds in the same way. Coverage turns on the specific policy language, limits, exclusions, waiting periods, definitions of a security failure and the facts of the incident.
Prior incidents and disclosure matter
A business that has already suffered ransomware should expect insurers to ask what happened and what changed afterwards. This is not merely an underwriting obstacle. It is an opportunity to demonstrate that the company has reduced its exposure through documented improvements.
Keep records of the incident timeline, forensic findings, remedial work, patching, password resets, MFA deployment, backup testing and staff training. When renewal discussions arise, evidence is more persuasive than a broad assurance that “the issue was fixed”.
Failure to answer insurance proposal questions accurately can create coverage disputes. If a question asks whether the business has experienced a prior cyber event, disclose it honestly and explain the remediation. A specialist broker can help interpret proposal questions, but they cannot make an incomplete answer safe.
Check whether business interruption reflects your real exposure
For many SMEs, the largest ransomware cost is not the ransom: it is lost trading. A manufacturer may be unable to schedule production; an accountancy firm may lose access to deadlines and client files; an online retailer may be unable to accept orders; a care provider may have to revert to time-consuming paper processes.
Assess how long critical systems could be unavailable and calculate the financial consequences. Review the policy’s indemnity period, waiting period and business-interruption limit. A low limit may look affordable but be inadequate if recovery takes several weeks and the business must pay overtime, alternative technology costs and continuing payroll.
Understand the insurer’s incident-response process before an event
Many cyber policies require or strongly encourage the insured to contact a designated breach-response helpline before appointing lawyers, forensic firms or negotiators. This can be beneficial: approved specialists are available rapidly and costs are more likely to be managed within the policy terms. But it also means staff must know who to call at 2 am on a Sunday, not just during office hours.
Put the insurer’s claims contact details into the incident-response plan. Name a deputy decision-maker, because the owner or IT lead may be unavailable during an attack. Confirm who can authorise emergency expenditure and who is permitted to communicate with customers, regulators and the media.
Practical steps to reduce the likelihood and impact of a repeat attack
No single technical control stops all ransomware. The most effective approach is layered and disciplined.
1. Make multi-factor authentication non-negotiable
Deploy MFA for email, remote access, cloud administration, finance systems and privileged accounts. Prioritise phishing-resistant methods where feasible, rather than relying solely on SMS codes. Remove inactive accounts and ensure staff do not share administrator credentials.
2. Test backups as a recovery capability, not a compliance tick-box
Maintain backups that are separated from the main network, protected against deletion and tested through actual restoration exercises. A backup that exists but cannot restore a key application, database or configuration is not a recovery plan.
Document recovery priorities. The first system to restore may be payroll, order processing or a clinical record platform—not necessarily the largest server.
3. Patch internet-facing and high-risk systems quickly
Maintain an asset inventory and identify which systems are exposed to the internet. Apply critical security updates promptly, particularly for VPNs, firewalls, remote-management tools and email platforms. If legacy software cannot be patched, isolate it and set a replacement timetable.
4. Rehearse an incident response plan
Run a tabletop exercise involving leadership, IT, finance, HR and communications. Work through realistic decisions: Who disconnects affected devices? How is evidence preserved? Who contacts the insurer? What happens if the attacker threatens publication of employee or customer data?
A rehearsed plan reduces the risk of improvised decisions that extend downtime or compromise insurance recovery.
5. Treat suppliers as part of the security perimeter
Ask managed service providers and critical software suppliers about MFA, backups, privileged access, breach notification and their own incident response arrangements. Limit supplier permissions to what they need and review access when contracts or staff roles change.
A better buying checklist for cyber insurance
Before purchasing or renewing cyber insurance, UK SMEs should compare policy wording and ask a broker or insurer practical questions:
- Does the policy provide 24/7 access to incident-response, forensic and legal specialists?
- Are ransomware, data exfiltration, restoration costs and business interruption expressly addressed?
- What are the sub-limits, excesses and waiting periods?
- Does the policy cover dependent business interruption where a key cloud or IT supplier fails following a cyber incident?
- Are social engineering or invoice-redirection losses covered, and under what conditions?
- What security controls are required, such as MFA, supported software, backups or endpoint protection?
- Are investigation and remediation costs covered after a suspected compromise, even if systems are not encrypted?
The most appropriate cover depends on the SME’s sector, revenues, dependence on digital systems, contractual obligations and data holdings. Cyber insurance should be reviewed alongside—not instead of—technical controls and continuity planning.
The strategic takeaway
The Hiscox warning should prompt UK SMEs to stop viewing ransomware as a single, contained crisis. A first incident can reveal weaknesses in access management, recovery processes, supplier oversight and executive decision-making. Unless those weaknesses are investigated and corrected, the business may remain exposed to the same group or a different criminal operation.
Insurance can provide critical financial and specialist support, but it works best when paired with tested backups, MFA, rapid patching, clear response roles and honest disclosure at placement and renewal. The goal is not only to get back online after an attack. It is to recover in a way that makes a repeat attack substantially harder and less damaging.
FAQ
Does cyber insurance cover ransomware payments for UK SMEs?
It may, but cover varies by policy and can be subject to conditions, sub-limits, insurer consent and legal considerations, including sanctions. Cover for forensic response, legal advice, restoration and business interruption can be as important as any extortion-related element. Check the wording rather than relying on a policy label.
Can my business obtain cyber insurance after a ransomware incident?
Yes, in many cases. Insurers will usually want to understand the incident, the root cause and the corrective actions taken. Clear records showing MFA deployment, patching, backup testing and security improvements can support a more informed underwriting discussion.
What should staff do first if they suspect ransomware?
Escalate immediately under the company’s incident plan. Isolate affected systems where it is safe to do so, avoid deleting evidence or communicating with attackers independently, and contact the designated IT lead and cyber insurer or broker. Use specialist incident-response guidance before making major recovery or payment decisions.
Is a cloud backup enough to protect an SME from ransomware?
Not necessarily. Backups need protection from unauthorised deletion or encryption, separation from normal user access and regular restoration testing. They should also support recovery of critical applications, configurations and data within a timeframe the business can tolerate.
