EU GDPR Compliance
The EU GDPR governs how organizations protect the personal data of people in the EU.
Learn how ImmuniWeb helps you meet its Article 32 security-of-processing obligations with
web and mobile application testing.
EU GDPR Compliance
What Is the EU GDPR?
The GDPR sets out how organizations may collect, use, store and transfer the personal data of individuals (data subjects) in the EU. It is built on principles such as lawfulness, purpose limitation, data minimization, accuracy, storage limitation, and integrity and confidentiality.
It defines the roles of data controllers and processors, grants data subjects extensive rights (access, rectification, erasure, portability and more), and requires organizations to demonstrate accountability. Crucially for security teams, it requires appropriate technical and organisational measures to protect personal data.

Who Must Comply with GDPR?
The GDPR applies broadly and extraterritorially:
- Controllers and processors in the EU that process personal data.
- Organizations outside the EU that offer goods or services to, or monitor the behaviour of, people in the EU.
- Any sector and any size — from startups to multinationals and public bodies.
Any organization that runs internet-facing web and mobile applications processing personal data must be able to show that those applications are secured and tested.
Key GDPR Requirements for Application Security
Several articles drive application-security work; the central one is Article 32:
- • Article 32 — Security of processing: appropriate technical and organisational measures, including encryption/pseudonymisation, confidentiality, integrity, availability and resilience, and a process for regularly testing, assessing and evaluating their effectiveness.
- Article 25 — Data protection by design and by default: building security and privacy into systems from the start (a secure SDLC).
- Article 5(1)(f) — Integrity and confidentiality: protecting personal data against unauthorised processing, loss or damage.
- Articles 33–34 — Breach notification: notifying the supervisory authority within 72 hours and, where required, affected individuals.
GDPR Security Requirements in Depth
Article 32 — Security of Processing
Article 32 expressly requires “a process for regularly testing, assessing and evaluating the effectiveness of technical and organisational measures”. In practice, this means penetration testing and vulnerability scanning of the web and mobile applications, APIs and infrastructure that process personal data — performed regularly and after significant changes, with findings remediated and re-tested.
Article 25 — Data Protection by Design and by Default
Security must be engineered in, not bolted on. Embedding security testing into the software development life cycle (DevSecOps / CI/CD) helps satisfy Article 25 and keeps applications secure release after release.
Common Web & Mobile Application Risks to Address
Most personal-data breaches happen through vulnerable web and mobile applications. The risks GDPR Article 32 expects you to prevent and test for map closely to the OWASP Top 10:
- Broken Access Control — users reaching data or actions they should not.
- Cryptographic Failures — weak or missing encryption exposing sensitive data.
- Injection — SQL, command or other injection via unvalidated input.
- Insecure Design — missing security controls by design, not just by bug.
- Security Misconfiguration — default, incomplete or unsafe configuration.
- Vulnerable & Outdated Components — unpatched libraries and frameworks.
- Identification & Authentication Failures — weak login, session or credential handling.
- Software & Data Integrity Failures — untrusted updates, insecure CI/CD pipelines.
- Security Logging & Monitoring Failures — attacks going undetected.
- Server-Side Request Forgery (SSRF) — the server tricked into making malicious requests.
For mobile apps, the OWASP Mobile Top 10 is the equivalent reference (insecure data storage, insecure communication, weak cryptography, and so on). Reliably finding these issues requires testing the running application, not just a documentation review.
How to Approach GDPR Application Security with ImmuniWeb
- Discover your assets. Inventory internet-facing apps, APIs and exposed data with ImmuniWeb Discovery (attack surface management).
- Test web applications with manual penetration testing (On-Demand) and automated scanning (Neuron).
- Test mobile applications with MobileSuite and Neuron Mobile.
- Remediate and retest with actionable, zero-false-positive reports — evidence of “regular testing” under Article 32.
- Embed testing in CI/CD with Continuous to support Article 25 (data protection by design).
- Monitor exposure with Discovery, including dark-web monitoring for leaked personal data.
How ImmuniWeb Helps You Achieve GDPR Compliance
ImmuniWeb supports GDPR's security-of-processing obligations with testing that produces clear, audit-ready evidence.
| Requirement | What it requires | ImmuniWeb products |
|---|---|---|
| Article 32 | Regularly test and evaluate the effectiveness of security measures protecting personal data. | On-Demand, Neuron, Discovery, Continuous |
| Article 25 | Build security into applications by design and by default (secure SDLC). | Continuous, Neuron |
| Apps & data exposure | Secure web/mobile apps processing personal data; detect leaks and exposed assets. | On-Demand, MobileSuite, Neuron Mobile, Discovery |
ImmuniWeb On-Demand delivers manual web application penetration testing with a zero-false-positives SLA; Neuron and Neuron Mobile provide automated scanning; MobileSuite covers mobile penetration testing; Continuous embeds testing into CI/CD; and Discovery maps your attack surface and monitors the dark web for leaked personal data.
GDPR vs International Frameworks
If you already work to international standards, the same ImmuniWeb testing supports all of them:
| Framework | Application-security angle | How ImmuniWeb maps |
|---|---|---|
| EU GDPR | Article 32 security of processing + regular testing | Web/mobile pentest, scanning, ASM, dark-web monitoring |
| UK GDPR | Equivalent security-of-processing duty | Same testing supports both |
| ISO/IEC 27001 | Annex A technical controls | Penetration testing & scanning as control evidence |
| NIST CSF 2.0 | Protect / Detect functions | Application testing & continuous monitoring |
Penetration Testing vs Security Scanning
Both are needed. Automated scanning (DAST) gives broad, frequent coverage and is ideal for continuous testing in CI/CD; manual penetration testing finds business-logic and complex vulnerabilities that scanners miss and produces the depth auditors and regulators expect. Combine continuous scanning with periodic manual penetration testing, and re-test after significant changes.
Compliance Checklist (Application Security)
- Inventory of internet-facing apps, APIs and exposed assets
- Web applications tested against the OWASP Top 10
- Mobile applications tested against the OWASP Mobile Top 10
- Security testing integrated into the SDLC (Article 25)
- Regular testing evidenced for Article 32
- Findings remediated and re-tested; records retained
- Dark-web / exposure monitoring for leaked personal data
Why GDPR Compliance Matters
GDPR carries some of the highest penalties in data protection — up to €20 million or 4% of global annual turnover — and regulators have shown they will use them. Beyond fines, a personal-data breach triggers 72-hour notification duties, regulatory scrutiny and reputational damage.
Because web and mobile applications are among the most exploited entry points, demonstrably testing them is one of the most effective ways to meet Article 32 and reduce breach risk. F
