Security built into every layer

Security is not an add-on.
It's built in from the start.

We design every part of your website with security in mind. Every connection is verified, every input is checked, and every layer is protected. So risks are handled before they become problems. The result is a website that stays secure, stable, and ready for compliance, without needing fixes after launch.

The three pillars of control and ownership

These are the principles that define how your website stays secure, transparent, and fully under your control. Not just in theory, but in how it actually works every day.

01

Data Integrity

Your data stays accurate, protected, and under control.

  • All data is validated and handled consistently this is reducing errors and preventing unexpected issues
  • Sensitive data is encrypted by default, both in storage and during transmission
  • Nothing critical is stored in the browser, all users are protected against common security risks
  • Every change is tracked, so data can be verified and restored if needed
  • Built with privacy standards in mind to ensure compliance from the start
02

Infrastructure security

Every layer is protected to prevent attacks before they happen.

  • Only trusted code is allowed to run. Filters are blocking malicious scripts automatically
  • Connections are secured and enforced at the browser level
  • Sensitive logic runs on the server, not exposed to users
  • Limits are applied to prevent abuse, spam, and attacks
  • All dependencies are checked for vulnerabilities before deployment
  • Access is limited to what's strictly necessary we are minimizing risk across the system.
03

Transparency and control

You always know how your system works.

  • Systems are designed to be clear and understandable
  • Everything is documented, tested, and verified before launch
  • You receive a full security report: what was tested, found, and resolved
  • Clear deployment checks ensure nothing is missed
  • Your system is built so your team can understand and trust it

Applied on every deployment

These checks are mandatory and applied on every release, not just once. So nothing is missed, and your system stays secure and reliable over time.

  • Core security checks applied on every deployment, based on OWASP Top 10 risks
  • Critical flows tested for vulnerabilities (authentication, payments, admin access)
  • Security protections verified on every release. This ensures browsers enforce safe behavior
  • Missing or invalid configuration blocks deployment. Issues are caught before the site is live
  • All dynamic content is secured to prevent code injection and common exploits
  • 90-day security guarantee on all delivered code. Fully covered, no fine print

Defense in Depth

Four layers. Nothing left exposed.

Each layer protects independently. If one is compromised, the others continue to protect your system.

All layers active in production

The Kynoku security standard

Our systems are not just secure, they are built to meet strict European security and privacy standards. Every layer is actively protected, tested, and verified on every deployment, not just once.

Designed to meet the expectations of European data protection laws and high-security environments.

Identity protection

Every user is verified. Nothing is trusted by default.

Secure authentication

By adding an extra layer of protection beyond password, users are verified with secure login systems that support multi-factor authentication by default.

Access control

We limit risk and preventing unauthorized actions across the system, by giving the access to each user only to what they need.

Secure integrations

We also prevent the interception and unauthorized access, by connecting safely third-party logins.

Session protection

User sessions are continuously secured and refreshed, preventing common attacks like session hijacking or reuse.

Transmission

Data in motion is data at risk. We eliminate the risk.

TLS 1.3 Encryption (Enforced)

All traffic is encrypted via TLS 1.3 with HSTS preload and includeSubDomains. Downgrade attacks are structurally impossible — not just discouraged.

Nonce-Based Content Security Policy

Every HTTP response carries a unique CSP nonce generated in middleware. Inline scripts without the correct nonce are blocked at the browser level.

Strict CORS Origin Allowlisting

Cross-origin requests are validated against an explicit allowlist. Wildcard origins are a build-breaking error in our CI pipeline.

API Payload Signing

Sensitive API transactions use HMAC-SHA256 payload signatures to guarantee integrity and detect tampering before any server-side processing.

Data in transit protection

All data moving through your system is encrypted and controlled.

Secure data transmission

To prevent interception or data leaks during the transmission, all data exchanges are encrypted using modern standards.

Protected code execution - AES-256 Encryption

Only trusted scripts are allowed to run in the browser. This ensures blocking malicious code before it can execute.

Controlled external access

External requests are strictly limited to trusted sources, preventing unauthorized systems from interacting with your application.

Data integrity protection

Sensitive data is verified before processing. We are ensuring it hasn't been altered or tampered with in transit

Active protection

Threats are detected and stopped at every level.

Continuous security monitoring

Prevent insecure code from going live, all components are checked for known vulnerabilities.

Abuse and attack prevention

Stop spam, brute-force attacks, and traffic abuse early, requests are limited and filtered before reaching your system.

Protection against code injection

Prevent malicious code from being injected or executed, all dynamic content is secured and validated.

Browser-level protections

For blocking unsafe behavior and reducing the risk of common attacks, security rules are enforced in every browser.

Compliance built in

Privacy and regulatory requirements are built into every layer of your website from the start, not added later.

OWASP Top 10

Core web security risks are tested on every deployment, ensuring your site stays protected against the most common vulnerabilities at all times.

GDPR / RGPD

Privacy is built into the system from the start. So data collection, consent, and deletion are handled correctly by default.

ISO 27001 Alignment

Security practices follow recognised international standards. It covers access control, system protection, and incident response.

Ready for security audits

Your system is built so it can be tested, reviewed, and validated at any time. Everything is structured, documented, and prepared for independent security audits, not fixed afterward.

Clear architecture which is structured and documented for easy review
Full documentation: including system diagrams, data flows, and security overview
Dependency insights: known risks are identified and addressed before deployment
Dedicated testing environment: ready for security audits and penetration testing
Rapid issue resolution: critical findings are fixed quickly and verified

In a digital environment you don't fully control, we give you the foundation to take that control back.

Your infrastructure isn't something to manage, it's something to own. We design it to be secure, transparent, and built for your long-term growth.

SECURITY CONSULTATION

Secure your website

Is your current system truly secure, or just assumed to be? In a world where discretion and data integrity matter, even small vulnerabilities can become real risks. Let's identify them before they become a liability problem.

What we review

  • Security and architecture audit
  • GDPR data protection alignment
  • Zero-Trust security strategy

Confidentiality

All conversations are handled with strict confidentiality. On-site meetings available in Nice and Monaco.

SYSTEM STATUS: SECUREDSTANDARDS: OWASP v4.0LOCATION: NICE/MONACO HUB
0 Critical issues

No critical vulnerabilities remaining after full security hardening across deployed systems.

A+ Security

Achieved through strict browser protections and secure configuration across all layers.

90-day coverage

All delivered systems are covered by a security guarantee. Issues are fixed at no additional cost.

Secure Your Website with Confidence

Let's review your current system, identify potential risks, and define how to improve its security, performance, and reliability.
