The systems your business runs on.
We design and build the software your company depends on, and we settle security in the design rather than patching it after launch. The same team that builds a system knows how to attack it, so the weak points surface with us, not with your customers.
What building securely actually means
Custom software means the program is shaped around your process, not your process bent to fit the program. It's worth it when the way you work is your advantage, or when an off-the-shelf tool covers only part of the job and you spend every day patching the rest with spreadsheets, email and re-typing.
Security is a requirement like any other in that work, not an add-on at the end. Who can reach what, where the sensitive data sits, what happens when a login is stolen: those questions belong in the design. Bolting the answers on later means rebuilding, and rebuilding always costs more than deciding it up front.
Building isn't always the answer. Often it's cheaper and faster to buy a ready-made tool, or wire two together, and when that's the case we'll say so plainly, even when it means a smaller job. When building does make sense, we take on the whole of it: design, development, going live and handover. The code is yours from day one.
Where security enters the build
It isn't one step at the end. It's four points along the work where it's decided whether the system holds.
- 01
In the design: threat modeling
Before code is written, we work through what the system has to protect, who would want to reach it, and what happens if they do. The design that comes out of that expects an attack, instead of meeting one with a patch later.
- 02
In the foundations: access and data
Sign-in, permissions, keeping customers' data apart, encryption, and a record of who did what. This is where most real damage originates, so we build it first, not as the last item before launch.
- 03
On every change
Every change goes through code review and automated tests. Third-party libraries are tracked and updated, because most vulnerabilities today do not come from your code, they come from what your code uses.
- 04
Before it goes live
Before anything reaches production, we try to break into it ourselves. What holds up ships; what doesn't gets fixed before it can reach you or your customers.
All of this is part of the development price and never billed afterwards. A standalone penetration test, security audit or red team engagement is additional specialist work: it belongs to our cybersecurity service and is billed separately. We'll recommend it where the system handles sensitive data, money, or where regulation requires it.
Different shapes of the same work
Most projects are a mix of two or three of these, depending on what's slowing you down most today.
Applications and portals
Applications, customer portals and dashboards that run in the browser, no install, reachable from anywhere. Built to hold up under real traffic and a real attack, and to stay maintainable long after launch.
Internal tools
The software that replaces the spreadsheet the whole business secretly runs on: admin, approvals, workflows and reporting, made to match how your team actually works, with permissions that make sense.
APIs and integrations
Connecting the systems you already run, accounting, warehouse, CRM, e-shop, so data flows once instead of being re-typed between them. We version the seams, document them, and check who is allowed to touch them.
Automation
The repetitive manual steps, moving data, generating reports, chasing statuses, get taken over by software: on a schedule, reliably, and with a record of what happened and who set it off.
Products and SaaS
If you sell software to your own customers, we build the parts that decide whether a subscription product survives: sign-in, keeping customers' data apart, billing and operations. Multi-tenancy is a security problem, not only a technical one.
Build, adapt, or buy?
The first question on any brief, and the most honest one. Not every problem needs new software. We walk through it with you before anything gets built.
| Approach | What it means | Cost | When it makes sense |
|---|---|---|---|
Buy off-the-shelf | Set up and configure an existing tool | Lowest | When your process is standard and a tool already exists that covers it. Nothing to build. |
Adapt and connect | Ready-made tools extended and wired together | Medium | When most of it is covered by something ready-made and only a piece is missing, or several systems need joining into one flow. |
Build custom | Software designed around your exact process | Highest | When the way you work is a competitive edge, or when a ready-made tool would cost you more in workarounds than it saves. |
We don't have a favourite route. We only have questions: what's actually slowing you down today, how much ready-made tools genuinely cover, which part is an edge you shouldn't hand away, and what data the system will hold. The answers decide whether anything needs building at all.
How it goes
We build in pieces, so after each stage you see a result and can decide whether to carry on, rather than waiting half a year for one big delivery.
Scope, risk and cost
We settle what the software should do, what it replaces, where it connects and what data it will handle. The build, adapt or buy decision is made here, openly, with the cost spelled out.
Design and threat model
Before the final code is written, we show a clickable design or a narrow prototype, and the threat model alongside it. A cheap moment to find out whether we understood each other, and to catch a hole while it's still on paper.
Building in pieces
We build in chunks that stand on their own. After each one you see progress and can say what to adjust while adjusting is still cheap. Every change goes through review.
Testing and launch
Before launch we test the system ourselves. Then going live, moving data over from the old setup, training and documentation. The code and the keys are yours.
Support and growth
After launch, monitoring, dependency updates, fixes and further features guided by what real use reveals. Or a full handover, if you'd rather run it yourself.
Common questions
What businesses and product teams ask us.
What does building securely mean? Doesn't everyone do that?
It means security is a requirement from day one, not a check at the end. We model threats during design, build access control and data separation first, review every change, and try to break in ourselves before launch. The more common approach is to build the features first and deal with security once someone finds something. By then it isn't a fix, it's a rebuild.
Is security included?
Secure practices are. They are a natural part of how we build, and we never bill for them afterwards. A standalone penetration test, audit or red team engagement is additional specialist work and is billed separately; we recommend it where the system handles sensitive data, money, or where regulation requires it.
Do you also build ordinary websites?
Not under voidsolutions. Marketing sites, landing pages and SEO are handled under our LumaWeb brand, which is built and priced for exactly that. What belongs here are the systems your business runs on: applications, portals, SaaS, integrations and automation. If you're not sure which side your project falls on, write to us and we'll tell you straight.
Can you take over a project someone else started?
Usually, yes. We begin with a review: architecture, the state of the code, how it's deployed, what holds it together and where the security holes are. Then we tell you honestly whether it's worth continuing, rebuilding part of it, or starting over. It's not unusual for us to recommend leaving it alone.
How long does it take, and what does it cost?
It depends on scope and we'll tell you after the first conversation. We aim to get a first usable version into production in weeks, not months. We bill in stages rather than one big number: scope and design first, then the first version, then growth. After each stage you know where you stand and can decide whether to carry on.
Who owns the code, and will we end up dependent on you?
The code is yours from day one, and we use widely adopted technology you can hire for. We write the documentation assuming someone else may read it. If our involvement ends, the software shouldn't notice.
Tell us what you're building.
A new system, a spreadsheet to replace, systems to connect, or a second opinion on what's worth building, send us a few lines and we'll reply within one business day.
