AI that works across your business
AI can help your business move faster, from building products and improving processes to security and workforce operations. Sunbytes applies AI where it creates value, with the right controls and people around it.
Before your product meets real users
You are about to launch, or you already have your first users. If AI helped you build your digital product, now is the time to review its security, architecture, reliability and deployment before more customers depend on it.
When growth adds work faster than it adds revenue
More demand often brings more manual steps, handoffs and approvals. Instead of simply adding people, we look at how the work gets done and automate the parts worth automating to improve productivity, consistency and quality, while keeping human judgment where it matters.
When growth demands more from your product
More users, larger customers and higher expectations put new demands on the product behind your business. We strengthen the architecture, reliability and delivery foundations that need to grow with it, without defaulting to a rebuild.
Less vendor complexity
More accountability
One partner across workforce, cybersecurity and business solutions, Dutch-led with delivery and talent capacity across markets.

One partner,
fewer handoffsWhen a business challenge crosses workforce, security and technology, you do not need to restart with a new provider every time.
Sunbytes can bring the right capability into the same engagement while keeping ownership clear.
-
Dutch-led,
globally capableClear accountability from Dutch-led leadership backed by delivery and talent capacity across the market.
Use the setup that fits the work without being limited to one delivery location.

Built around
control and evidenceStructured delivery, defined ownership & documented processes sit behind the work, supported by an ISO 27001-certified management system.
Sunbytes operates with an ISO 27001-certified management system and a brand framework.
-
Start from
where you need usBegin with one immediate need, whether that is hiring, security, automation or product delivery, and bring in additional capabilities only when relevant.
No need to buy the whole Sunbytes service portfolio to start.
-
Built for
long-term continuitySunbytes can stay involved as your needs change, rather than treating every new requirement as a separate project or vendor search.
That matters when a product grows or an engagement develops into operational support.
-
Capability beyond
one disciplineBusiness problems rarely stay inside one function. A hiring issue can become an employment problem. A product issue can expose security gaps.
We bring the workforce, security & technical expertise into the same business context.

Testimonials
“Sunbytes’ in-depth knowledge and resources helped us several times to make the right decisions for the next stages of the projects.”
“Sunbytes’ ease of communication and efficiency of project work are impressive. The team is very smart, reliable, and independent, they’re the ideal partner for us.”
“Working with the Sunbytes team has given me the benefit of working with flexible well-trained developers without losing control over the project, scope, and impact.”
“We are impressed with the skill set the Sunbytes engineers have. They are experts in multiple areas of web development, and that provides us with a well-rounded knowledge base to pull from.”
“SunBytes is pragmatic, a pleasure to work with, and the communication with both engineers and management has made them direct members of our own team.”
“Sunbytes delivered exactly what we needed. They hit every target, managed the project smoothly, and kept everything on track with clear communication and regular feedback.”
“Sunbytes started to assemble the team at their own risk even before we had our seed investment signed. When that happened we could make a flying start.”
“We were impressed by the vulnerabilities that were discovered. We can tell that the pentesters dug deep to discover the vulnerabilities, and not just a surface scan.”
“Sunbytes’ thorough approach uncovered risks we’d never even considered and opened my eyes to just how important it is to secure our platform from day one.”
“Sunbytes has put a lot of effort in understanding our needs by having in-person conversations and most importantly, by asking the right questions.”

Customer success is our priority
Eight roles hired in two months, quality held
Open technical roles were blocking delivery, and quality could not be traded for speed. Sunbytes ran needs assessment, sourcing and technical screening to fill the whole slate.
8 positions filled · 4 developers, 2 testers, 1 QA · 2 months
One global site that performs the same in 21 languages
Marketing campaigns outpaced internal dev capacity. Sunbytes took on site performance, DevOps and code review so releases stayed on schedule across every localized version.
600k+ customers served · 21 localized versions · 8 engineers
A pentest that dug past the surface, before launch day
A new authentication mechanism needed validation before launch. Sunbytes ran a grey-box pentest against OWASP Top 10 and CREST, then walked the team through remediation.
Grey-box pentest · SOC2 & ISO report · 9 findings classified
Mismatched stacks became one platform, with no downtime at peak
A fragmented portfolio of publisher sites ran on mismatched stacks. Sunbytes consolidated them onto one headless platform built to absorb campaign-driven traffic spikes.
50M+ monthly visitors · 100+ features shipped · 9 engineers
Price and invoice checks that once ate days, now automated
Staff compared vendor pricing and invoices by hand, slowly and with errors. Sunbytes built a dashboard, a price comparison engine and an EDIFACT invoice parser to remove the manual step.
800k products processed daily · 150k invoices automated · 10+ suppliers
A full platform relaunch without losing a single subscriber
The platform needed a full rebuild while staying live for subscribers. Sunbytes handled frontend, backend and an AI chatbot, then stayed on for continuous optimisation.
Revenue up 25% · 3,005 new users in 2025 · 4-year partnership
Secure cloud platform, architecture to prototype in 3 sprints
A post-quantum authentication scale-up needed a secure cloud platform and a team to build it. Sunbytes assembled seven specialists and shipped a working prototype fast.
Prototype in 3 sprints · 15 releases · 3,380 test cases
Launched on time and secure, six weeks from test to fix
An education platform handling pupil data was weeks from launch with no in-house security team. Sunbytes ran a black-box pentest and mapped findings to GDPR, NIS2 and ISO 27001.
6-week test-to-fix cycle · GDPR, NIS2, ISO 27001 · Launched clean
Legacy and modern stacks, shipping in sync for six years
Dozens of high-traffic news sites ran across modern and legacy stacks at once. Sunbytes took on bug mitigation, SEO and WordPress feature work to keep every sprint on time.
6 engineers · 6-year partnership · Tens of millions of monthly users
An awkward legacy CMS, rebuilt and migrated in five months
A research database sat on an unconventional CMS with a difficult interface. Sunbytes rebuilt it on WordPress, migrated every record across and reworked the user flows.
5-month delivery · Full legacy migration · Delivered on schedule

IT staff augmentation from Vietnam: what European companies need to know
Vietnam is a delivery-fit decision before it is a rate decision. For European companies, IT staff augmentation from Vietnam works when internal product ownership is strong, senior external engineers can enter an existing delivery system, and the working day creates enough shared time for decisions. The location is a poor fit when the buyer expects […]

IT staff augmentation security: ISO 27001, GDPR and vendor due diligence
An NDA covers confidentiality. It does not decide who can enter production, whether a developer may download customer data, or how quickly access disappears when an engagement ends. Those controls must exist before the first sprint. IT staff augmentation security is the set of contractual, technical and operating controls that govern how external developers access […]

Building a security-first engineering culture in distributed teams
A security-first engineering culture is an operating model in which developers can see who owns a security decision, when a review is required and where the result must be recorded. It is not a slogan, a yearly course or a request for every engineer to become a security specialist. That distinction matters across locations. A […]

How many DevSecOps engineers does a mid-size SaaS need?
The useful DevSecOps team size question is not “How many security engineers should we hire?” It is “Which security responsibilities need continuous ownership, and how much capacity does that work require?” Two SaaS companies with 100 employees can need very different setups. One may run a single product on one cloud platform. The other may […]

In-house vs outsourced DevSecOps: cost, risk and speed comparison
The wrong DevSecOps operating model creates work in the place it was meant to remove. An internal hire can become a single point of dependency. An external team can generate findings without giving developers a clear remediation path. This in-house vs outsourced DevSecOps comparison focuses on the decision that matters: which model gives your company […]

IT Staff Augmentation Contract: What to Include and Watch Out For
An IT staff augmentation contract is not just a capacity order. It is the document that decides who controls delivery once an external developer has access to your codebase, your customer data, and your sprint board. Most disputes in staff augmentation engagements trace back to one of five gaps: vague scope, unclear IP assignment, missing […]
