With the rise in cyber security breaches information security is now a critical business activity. Cyber threats are growing in number, sophistication, and impact, while organisations are under increasing pressure to protect sensitive data, meet regulatory requirements, and maintain customer trust.  
 
For many businesses, however, building and maintaining a full in-house security team is costly and complex. This is where InfoSec as a Service (ISaaS) comes in, we explain more in this article.

Understanding InfoSec as a Service

Think of ISaaS (InfoSec as a Service) as having a virtual security department that scales with your business needs without the overhead of building everything yourself. Instead of hiring, training, and managing an internal security team, companies gain access to experienced security professionals, tools, and processes on demand. This is a subscription-based or managed service model in which organisations outsource some or all of their information security functions to a specialised third-party provider.

Why organisations choose ISAAS

There are several factors driving the adoption of InfoSec as a Service: 

  • Rising cybersecurity threats – Cyberattacks such as ransomware, phishing, and data breaches are becoming more frequent and damaging. Organisations need continuous monitoring and rapid response capabilities that are difficult to maintain internally.
  • Cost efficiency – Hiring a full-time security team and purchasing enterprise-grade tools can be prohibitively expensive, especially for small and mid-sized businesses. ISaaS offers predictable costs and better ROI.
  • Regulatory and compliance pressure – Frameworks and regulations like ISO 27001, SOC 2, GDPR, HIPAA, and PCI DSS require ongoing security controls and documentation. ISaaS providers often specialise in helping organisations meet these requirements. An example of a provider like this would be ISMS.online who we work closely with and will introduce later in this article.

Core components of InfoSec as a Service

While offerings vary by provider, most InfoSec as a Service solutions cover a core set of ongoing security capabilities designed to reduce risk and support business growth. These typically include: 

  • Security strategy and governance, such as security program design, risk assessments, policy development, and virtual CISO support 
  • Continuous monitoring and detection through SOC services, threat intelligence, and endpoint and network monitoring 
  • Vulnerability management, including regular scanning and risk-based remediation guidance 
  • Incident response, with support for detection, containment, and post-incident analysis 
  • Compliance and audit support to help organisations prepare for assessments and maintain ongoing compliance 

How IsaaS and ISMS.online work together

A strong security programme requires both expert guidance and effective tooling. That’s why we work closely with ISMS.online to help organisations not only become compliant but stay compliant. 

ISMS.online provides a purpose-built platform for managing information security and compliance frameworks such as ISO 27001, SOC 2, and GDPR. It centralises policies, risk management, asset registers, evidence collection, and audit workflows in one place. 

Our InfoSec as a Service offering complements ISMS.online by providing the people and expertise behind the platform. Together, we help you: 

  • Design and implement a compliant ISMS aligned to your business 
  • Configure and use ISMS.online effectively from day one 
  • Develop policies, risk registers, and controls that meet audit expectations 
  • Maintain continuous compliance through ongoing oversight, reviews, and improvement 
  • Prepare for certification and audits with confidence 

In short, ISMS.online provides the structure and visibility, while our ISaaS team provides the hands-on security leadership and operational support needed to make compliance achievable and sustainable. 

How ISaaS differs from traditional security models

Traditional security models often rely on in-house teams, one-time assessments, and standalone tools, which can leave organisations reacting to issues as they arise. In contrast, InfoSec as a Service delivers continuous, scalable protection backed by experienced security professionals and proven processes. Rather than focusing on isolated fixes, ISaaS emphasizes proactive risk management and ongoing improvement as the organisation grows.

Who benefits most from InfoSec as a Service?

InfoSec as a Service is particularly well suited to organisations that need robust security capabilities without the complexity of managing everything internally. These include: 

  • Small and mid-sized businesses without dedicated security teams 
  • Startups preparing for customer or investor security requirements 
  • Growing organisations facing new compliance obligations 
  • Enterprises looking to augment existing security capabilities 

Beyond who it serves, ISaaS delivers clear business value. It helps organisations reach security maturity faster by providing access to specialised expertise and proven processes, while offering predictable, scalable costs. At the same time, ISaaS improves visibility into security risks and strengthens an organisation’s overall compliance posture.

As cyber risks continue to evolve, InfoSec as a Service is expected to become a standard operating model for many organisations. With advancements in automation, AI-driven threat detection, and integrated compliance tooling, ISaaS will play a central role in helping businesses stay secure in an increasingly hostile digital landscape. Whether you’re just starting your security journey or looking to strengthen an existing program, InfoSec as a Service may be the solution that fits your needs. Contact our team who can help.
