Why SaaS pentesting
is important
Identifying vulnerabilities
before attackers exploit them
The Software-as-a-Service (SaaS) industry is constantly growing, which makes it an attractive target for cyber threats. According to the 2024 State of SaaS Security Report by AppOmni, 31% of global businesses were breached via SaaS applications last year.
With large volumes of sensitive data stored and processed every day, SaaS products and businesses face a significant risk, as a major breach could irreparably damage the trust of customers and threaten the legal and financial position of the business.

Cyber security challenges faced by
SaaS companies in the UK
From misconfiguration
to third-party risks,
secure every layer

Multi-tenant architectures
and shared data
SaaS platforms are often built as a multi-tenanted environment, meaning many customers share the same infrastructure and endpoints. While this provides a cost-effective, consistent and scalable solution, it also presents a complex security challenge, as serious vulnerabilities cannot easily be isolated or contained. Securing these shared environments requires a comprehensive access control layer, which can often result in oversights due to the complexity of access controls.

Rapid development
and deployment
SaaS businesses are under constant pressure to maintain development velocity and deploy new features and improvements rapidly to keep up with competition. Whilst most mature SaaS businesses have high performing Continuous Integration and Continuous Deployment (CI/CD) pipelines, manual review and testing is still critical to ensure quality and security, whilst being a painful bottleneck due to resource constraints and competing priorities.

Third-party integrations
and supply chain
SaaS platforms often leverage third-party integrations for features such as payment processing and customer relationship management (CRM). Business-to-Business (B2B) applications can have even more complex integrations with accounting software, external data sources, code repositories and resource planning/management tools. Each of these third-party services and integrations presents its own set of potential vulnerabilities, and must therefore be thoroughly security tested.

Code maintenance and
legacy libraries
SaaS development teams must keep abreast of major changes and security announcements affecting libraries in their code base. Large projects often use hundreds of external libraries, and keeping on top of these packages is a big task. Whilst many tools exist to automate library management, vulnerability reports often need manual risk assessment and treatment, and it is often difficult to ascertain whether a vulnerability could be exploited in practice.

Why UK SaaS companies prioritise
penetration testing for cyber resilience
Protect data, trust
and business growth
with proactive testing
The SaaS model depends on trust. Whether it’s Personally Identifiable Information (PII) or sensitive business information, your customers and users entrust you with their most valuable assets. Protecting that data is critical to maintain compliance and to be trusted by customers. The average cost of a data breach is over £4 million, according to the IBM Cost of a Data Breach Report 2024, and this doesn’t account for the long-term damage to brand reputation and customer loyalty.
Moreover, SaaS companies are responsible for managing data under regulatory frameworks such as GDPR, HIPAA, and PCI-DSS. Non-compliance can result in hefty fines and legal challenges.
