Services / Application security and GDPR
Application security and GDPR, from the first line of code
Security is not a certificate added at the end: it is a discipline applied to the code from the very first line. Software built secure following OWASP standards and GDPR-compliant by design, so it is born protected instead of being made compliant afterwards. And, where needed, the review and hardening of applications that already exist.
What application security means
Application security means protecting software from the inside: in the way it handles data, access and errors. It is not a product to install or an SSL certificate added at the end, but a discipline that accompanies development from the first line, referencing OWASP standards.
The cost of finding out later
A vulnerability found in production costs far more than one avoided during development: it can mean a data breach, a GDPR fine, reputational damage. Building secure from the start reduces the exposed surface and the risk, instead of chasing flaws one at a time.
What gets done, in practice
- Validating every piece of data that comes in, to stop injections before they do harm.
- Handling authentication and permissions properly, with least privilege.
- Covering the most critical application risks, referencing the OWASP Top 10.
- Collecting the minimum data needed (data minimization).
- Secure deployment and configuration: no secrets in the code, no doors left open.
The work takes two forms: new software built secure by design, and reviews (audits) of existing applications, to find and close the weak points before someone else does.
GDPR by design, not made compliant later
GDPR is not a form to fill in at the end: it is a way of designing. Collect only the data that is needed, protect it where it is stored and while it travels, track who accesses it. Software designed this way is born ready for compliance, and compliance is not a patch but a consequence of how it is built.
The proof is this site
The simplest demonstration is the page you are reading: it is cookieless, with no trackers or third-party services, with strict security headers and a tight Content-Security-Policy. The method is not described, it is applied here.
A website with no cookie banner: it can be done, and it is better
What is not included
In fairness: the scope is application security and GDPR compliance in development. It does not include managed security services (continuous monitoring, SOC), network defence (firewalls, detection systems), or penetration testing sold as a standalone service: those need specialised people and providers. Knowing where one competence ends and another begins is part of doing the work well.
How it starts
For new software, security is included in the method. For an existing application, a low-cost review identifies the weak points and the priorities. From there, a phased quote with costs and timelines set before starting.
Frequently asked questions
What is application security?
It is protecting software from the inside: how it handles data, access and errors. It is not a product or a certificate added at the end, but a discipline applied to the code during development, following OWASP standards.
What does «GDPR by design» mean?
That the software starts from a compliant baseline: it collects only the data needed, protects it and tracks access from the design stage, instead of being made compliant afterwards.
Can an application that already exists be secured?
Yes. A review identifies the weak points, from missing validation to over-broad access, and closes them by priority, with a phased plan.
Are penetration testing or network security included?
No: the scope is application security and GDPR in development. Managed monitoring, network defence and penetration testing as a standalone service require specialised people.
How do you prove the method works?
This very site is the proof: cookieless, with no third parties, with strict security headers and a tight Content-Security-Policy.
