Cybersecurity Importance

What Are Cyber Security Services?

Cyber security services for small business are ongoing protective measures designed to reduce the risk of data loss, system compromise and operational disruption, without the cost or complexity of building an in-house security team.

Your Cyber Foundation

Cyber Essentials

Cyber Essentials is often the first formal security standard an organisation adopts and, increasingly, a commercial requirement.

Cirrus Security takes responsibility for guiding organisations through certification and ensuring the required baseline controls are properly implemented and maintained across access, devices, patching, and malware protection.

For growing organisations, it provides a recognised foundation that supports credibility, reduces risk, and enables sustainable growth.

Certification demonstrates to enterprise clients, regulators, and insurers that security is managed with discipline and oversight.

Global Standard

ISO 27001

ISO 27001 establishes a structured and accountable framework for managing information security as the business scales.

Cirrus Security takes responsibility for implementing and maintaining an Information Security Management System that defines risk, assigns ownership, and embeds control across the organisation. Security governance becomes measurable, reviewed, and aligned to recognised standards.

Where a higher level of assurance is required, Cyber Essentials Plus extends this foundation through independent technical verification. Cirrus manages the additional assessment process to ensure that implemented controls withstand external testing and formal validation. This provides strengthened evidence to enterprise clients, public sector bodies, and insurers that security controls are not only declared, but demonstrably effective.

Eliminate Uncertainty

Penetration Testing & Assessment

In addition to our recognised certifications, Cirrus Security can deliver a wider programme of security scans, health checks, and vulnerability testing tailored to your environment and the level of assurance you need.

Some organisations want extra confidence beyond the baseline. Others have to satisfy external governance requirements — client questionnaires, insurer scrutiny, internal audit, supplier onboarding, or tender frameworks. In those cases, “we think we’re covered” isn’t enough. You need evidence, presented clearly, with priorities that the business can act on.

That’s where we come in. We assess your security posture using structured testing and review, then translate the findings into a plan that improves security and stands up to scrutiny.

Network and Endpoint Protection

Managed Firewall and Endpoint Security Services

A firewall is only as good as the team monitoring it. Cirrus delivers managed firewall services and endpoint security services that protect your business 24/7, combining technology, monitoring, and structured response so threats are caught before they cause damage.

Our managed firewall service includes configuration, ongoing rule management, threat monitoring, and regular reviews. Endpoint security extends that protection to every laptop, desktop and mobile device used across your organisation.

The result is layered protection that adapts as your business grows, without leaving gaps that attackers can exploit.

Frequently asked questions

What's included in cyber security services for small business?

Our cyber security services for small business include managed firewall, endpoint security, email protection, network monitoring, user awareness training, and certification support including Cyber Essentials and ISO 27001. Each service is scaled to match your size, risk profile and budget.

Do small businesses really need cyber security services?

Yes. Small businesses are now the most targeted group for cyber attacks because attackers assume defences are weaker. Cyber security services close that gap by providing enterprise-level protection without the cost of an in-house team.

What is a managed firewall service?

A managed firewall service means an external provider takes responsibility for configuring, monitoring, and maintaining your firewall, including rule changes, threat detection, and regular reviews. It removes the burden from your internal team while improving response times.

How long does Cyber Essentials certification take?

Most organisations achieve Cyber Essentials within 2–6 weeks depending on the maturity of existing controls. Cyber Essentials Plus typically takes longer due to independent technical verification. We guide you through the full process from gap analysis to certification.
