For many organisations, annual penetration testing remains the primary method of assessing web application security.
While penetration testing remains valuable, modern development cycles, API adoption, cloud-native applications and continuous releases have changed the reality of web security exposure.
The question organisations increasingly need to ask is:
What happens to your applications during the other 51 weeks of the year?
Many businesses successfully complete an annual penetration test and assume their external attack surface remains protected until the next assessment cycle.
In reality, vulnerabilities can appear within days — or even hours — of a release.
Modern applications evolve constantly:
Each change introduces the potential for new exposure.
Without continuous visibility, organisations often operate with long periods of unmonitored risk.
As one recent API security analysis noted:
“A traditional penetration test is a snapshot.”
That snapshot becomes outdated quickly in environments where applications and APIs continuously evolve.
Web applications and APIs continue to represent one of the most common entry points for attackers.
OWASP notes that APIs now underpin modern SaaS, mobile and cloud-native applications, exposing sensitive data and application logic that increasingly attract attackers.
Threat actors increasingly target:
API security has become especially important because many organisations lack consistent visibility into:
A CSO Online report previously highlighted that APIs accounted for a significant proportion of the web attack surface as API-driven architectures expanded.
One of the most common issues organisations face is the growth of Shadow IT.
Development teams frequently:
Without continuous monitoring, these assets often remain:
This creates significant operational and compliance risk — particularly for organisations working toward:
Security misconfiguration alone remains one of the most common API risks identified by OWASP.
Continuous web application and API scanning provides organisations with ongoing visibility rather than point-in-time assurance.
Instead of waiting months for the next assessment cycle, security teams can identify:
within hours of exposure.
Modern DAST platforms such as AppCheck are designed to:
In many cases, complete scans can be completed within a single working day depending on application complexity.
Security researchers and practitioners increasingly recognise that static testing schedules struggle to keep pace with modern development environments.
Security and IT teams should regularly assess:
These questions are becoming increasingly important as organisations move toward continuous delivery and API-first architectures.
Penetration testing remains an important part of a mature security programme.
However, relying on annual testing alone creates long periods where vulnerabilities can emerge unnoticed.
As modern attack surfaces become increasingly dynamic, organisations require:
to keep pace with evolving threats.
Peritus Cloud Security helps organisations improve visibility across web applications and APIs through continuous vulnerability assessment and remediation support.
Using AppCheck, Peritus helps identify:
while providing clear remediation guidance aligned to operational and compliance requirements.
Peritus can provide a lightweight vulnerability assessment across one of your externally facing applications to help identify:
with minimal operational overhead.
