Secure design
Security architecture designs your protection from the ground up, in layers and from the start, instead of sticking patches onto something already built. We define how your network is segmented, who accesses what, how the cloud is protected and how defences are arranged so that, if one layer fails, the rest hold. Security planned in advance costs less and resists better than security added afterwards.
Segmentation, identity, cloud and defence in depth, designed to fit you, across Spain.
Why
Adding protection onto something already built is expensive and leaves gaps. Planned from the design, security comes out better, cheaper and far harder to knock down.
What gets added on top of a system already running costs more, fits worse and always leaves cracks.
If your whole defence is the perimeter and it falls, everything behind it is left open. That is why it is designed in layers.
The cloud, remote access and suppliers have erased the clear border. The design has to be rethought.
Systems that grow by accumulating add-ons end up fragile and impossible to defend properly.
What we design
It is not a single control, but how everything fits together, from the outside in: the perimeter, the network, access, the data and the cloud, designed to support one another.
Controlling what is exposed to the Internet and how to protect what has to be accessible.
Dividing the network so that a problem in one place does not spread to everything else.
Who gets into what, verifying every access with a Zero Trust approach and granting least privilege.
Encryption and control over the information, so that the data stays safe even if someone reaches it.
Cloud architectures well configured from the start, whether with one provider or in multicloud.
A clear, documented model that your team can follow, maintain and grow.
The approach
We do not copy an off-the-shelf architecture. We start from what you do and what is at stake, and from there we decide where to place each layer and how much protection it needs. What is critical is hardened; what is not does not load the system with controls it does not need.
We design on principles that hold up: least privilege, not trusting by default and never depending on a single control. That way the design responds to your risk analysis and leaves a solid base on which to build the rest.
Versus improvising
Almost any system can be protected in two ways. Only one pays off. Here is how the difference shows.
Controls added when something fails or when an audit asks for them, one on top of another and without a common plan. Costly to maintain, full of gaps and hard to explain.
Defences planned from the start and fitted together, in layers and with a common criterion. Cheaper in the long run, more solid and easy to maintain and grow.
Security by Design
We work with the Security by Design approach: security enters the first sketch of the system, not as an add-on at the end. And we pair it with Security by Default, secure out-of-the-box configurations and the smallest attack surface, so that the secure option is the one that comes by default and not something someone has to remember to switch on.
To get the design right we do threat modelling: we put ourselves in the attacker's shoes before building, to see where they would come from and close those routes already on the drawing board. On top of that, the principles that have proven themselves for years: defence in depth, least privilege and Zero Trust, aligned with frameworks like OWASP, NIST or ISO 27001.
And it is not just good practice: the Cyber Resilience Act requires Security by Design in products with digital elements and the GDPR mandates protection by design and by default. Designing well is, on top of that, compliance.
When
A new system, product or platform: it is the best moment to design them secure from the start.
A migration or a new cloud environment that is worth designing well before filling it with data.
Years of add-ons have left a fragile architecture that now costs more to maintain than to rebuild sensibly.
An attack has shown that the problem was not a loose control, but how everything was designed.
Method
Your business, your risk and what you already have in place, to design on reality and not on paper.
The layers, the zones and the access, with threat modelling to anticipate where they would attack and a clear model your team understands.
We support the rollout, in phases and without stopping what already works.
We check that the design really holds, putting it to the test before signing it off.
Fits with
The architecture is the blueprint: it responds to your risk analysis, organises what the master plan sets out and is validated with a pentest that checks the design really holds.
And it comes down to the ground: secure design reaches development with DevSecOps, extends to the plant floor when OT security is involved, where segmentation rules, and what we design is then watched over by Sondriva, our SOC.
Questions
It is the design of how your organisation is protected from the ground up: how the network is segmented, who accesses what, how the cloud is protected and how defences are arranged in layers, so that security is built in from the design and not bolted on with patches afterwards.
Zero Trust starts from not trusting anyone or anything by default, inside or outside the network. Every access is verified and granted with least privilege, instead of assuming that everything already inside the perimeter is safe.
Yes. We design security architectures in the cloud, well configured from the start, whether you work with a single provider or in hybrid or multicloud environments.
No. It is improved in phases, on top of what you already have, starting with what is most exposed and concentrates the most risk. The goal is to gain security without stopping your operation.
The architecture designs the defence; the pentest puts it to the test. One builds and the other checks that it holds. The ideal is to design well and then validate it with offensive testing.
Security by Design means building security in from the first sketch of the system instead of adding it with patches at the end. It includes secure default configurations (Security by Default) and threat modelling in the design phase, and it is what the Cyber Resilience Act and the GDPR require.
