Cyber Security as a Service (CSaaS) for UK Businesses.
Acting as an extension to your team, we build defences and monitor your systems for cyber incidents 24x7x365.
What is Cyber Security as a Service?
Cyber Security as a Service (CSaaS) is a subscription-based model that delivers ongoing cyber security protection, expertise, and tooling as a managed service. Unlike traditional cyber security consulting, which is often project-based, time-limited, and reactive, CSaaS provides continuous, scalable support for your organisation month to month and acts like an extension of your internal team.
CSaaS typically includes services such as a virtual Chief Information Security Officer (vCISO), vulnerability management and penetration testing, security monitoring and incident response, security awareness training, and compliance support for frameworks and certifications like ISO 27001 and SOC 2. It is designed for organisations that need strong security outcomes without the cost, complexity, or delay of building and maintaining a full in-house security function, especially SMEs, growing teams, and regulated businesses.
Also Known As
Cyber security as a service is also known as managed security services, managed cyber security, or security as a service (SECaaS). You may also see providers referred to as MSSPs (Managed Security Service Providers). These terms all describe the same model: outsourced, subscription-based cyber security delivered by a specialist team.
What's Included in Cyber Security as a Service?
Virtual CISO
Our vCISO will take ownership of security defining and driving the cyber strategy, ensuring traction is built and maintained across the business.
Incident Response
Our UK-based Security Operations Centre (SOC) monitors your network and systems (e.g. AWS) for threats, investigates incidents and responds quickly.
Security Awareness
We identify high-risk roles and provide memorable training and impactful comms to raise awareness amongst your staff and executive.
Secure Software
We will help maintain robust security within your software development lifecycle ensuring that historic and newly developed code is secure and resilient.
Third Party Due Diligence
We handle the due diligence questionnaires you receive from prospects and clients, ensuring you respond quickly and shorten sales cycles as a result.
Assurance & Testing
Each year we conduct a cyber maturity assessment (measuring strategic progress, identifying risks and areas of improvement) and conduct a penetration test of your IT infrastructure.
Challenges CSaaS Solves
Limited Time
You need to focus on your customers and growing your business. You don’t have the time required to dedicate to building cyber security and consequently, cyber security unintentionally becomes an afterthought, increasing the risk of an attack that may result in significant financial and reputational damage.
Lack Of Expertise
Cyber security is a complex field that encompasses a wide range of skills, from threat detection and incident response to compliance management. In-house IT staff lack the specialised cyber security expertise required to address the full spectrum of digital risks, leaving their business vulnerable to cyber attacks.
Cost Contraints
You’re committed to protecting your business, but you don’t have the unlimited budgets of large enterprises. Maintaining a full-time team puts pressure on your bottom line. With Cyber Security as a Service, the up front investment is minimal and can be scaled up or down as required.
Increasing Threats
2024 saw a 75% increase in successful cyber attacks on cloud technologies. For most SMBs without Cyber Security as a Service, continuously monitoring the threat landscape and investing in the right controls to maintain the level of protection needed (whilst also focusing on growth) is an impossible task.

CSaaS vs In-House Security Team
Many organisations compare Cyber Security as a Service (CSaaS) with building an in-house security function. The right choice depends on your risk profile, compliance needs, and how quickly you need coverage.
| Factor | CSaaS (Cyber Security as a Service) | In-House Security Team |
|---|---|---|
| Expertise | Access to a broad team of specialists (e.g., vCISO, SOC analysts, penetration testers, compliance experts) | Often relies on a single hire or small team, with gaps in specialist skills |
| Coverage | Can provide continuous monitoring and incident response, including 24/7 options | Typically limited to business hours unless you staff shifts and on-call rotations |
| Scalability | Flexible: scale up or down as your needs change (growth, new compliance demands, incidents) | Fixed capacity: scaling usually means recruiting, onboarding, and retaining more staff |
| Cost structure | Predictable subscription cost, aligned to required coverage and services | Higher fixed costs (salaries, benefits, training) plus tooling, recruitment, and overheads |

Cyber Security as a Service FAQs
- What is cyber security as a service?
Cyber Security as a Service (CSaaS) is a subscription-based service that provides ongoing cyber security expertise, tools, and operational support to protect your organisation. Instead of one-off consulting projects, CSaaS delivers continuous improvement and protection through a managed, scalable service.
- What does CSaaS include?
Core CSaaS services covers essential areas like: vCISO for strategic oversight and guidance, penetration testing for finding and fixing vulnerabilities, security monitoring & rapid incident response, compliance support, and employee training to reduce human risks.
- How much does cyber security as a service cost?
Costs depend on your organisation’s size, risk profile, compliance requirements, and the level of monitoring and response needed. Most CSaaS pricing is structured as a monthly subscription, which can be more predictable than hiring in-house roles and purchasing multiple security tools separately. For an accurate quote, CyPro usually scope your current environment, priorities, and required coverage.
- Is cyber security as a service right for my business?
CSaaS is a good fit if you need stronger security but do not want the cost and complexity of building a full in-house security team. It is commonly used by SMEs, growing businesses, and regulated organisations that need ongoing guidance, monitoring, and help meeting security and compliance obligations.
- What’s the difference between CSaaS and managed security services?
Managed Security Services (often called MSSP services) typically focus on monitoring and managing specific tools, such as SIEM, endpoint security, or firewalls. CSaaS is usually broader and more strategic, combining security leadership (like a vCISO), ongoing risk reduction, testing, training, and compliance support alongside operational monitoring and response. In other words, MSSP can be one component, while CSaaS is often a more complete security programme delivered as a service.
