About
Cybersecurity software development
Cybersecurity software development is the engineering of products that protect systems, applications, infrastructure and data. It pairs software engineering with cybersecurity domain depth to tackle problems that cross technologies and environments.
On The Spot Development builds teams across a broad range of cybersecurity domains: cloud and runtime security, application and software supply chain security (including code and CI/CD security), email and social engineering security, and AI and agentic security.
Who it's for
When a dedicated team for a cybersecurity product makes sense
01
You limit your roadmap by hiring in expensive markets like the US, Israel, or the UK. In Poland, you get the same seniority for less, with total transparency into the salaries you pay.
02
Your cybersecurity local talent market is narrow, the search runs for months, and your product roadmap scales fast. Time to hire is the constraint.
03
You need to stay flexible on headcount. You want the ability to scale and restructure the team fast based on changing project demands.
04
You need highly specialized, hard-to-fill roles like kernel and eBPF development, detection engineering, low-level Rust, and pipeline security.
Testimonials
This collaboration has improved development efficiency by over 40%, reduced costs, and supported strong revenue growth. The team’s expansion from 2 developers in 2019 to over 55 today has been key to accelerating product delivery and scaling our impact.

Why On The Spot Development
Why cybersecurity companies stay with us
Final hiring decision
We source and prescreen technically, then present profiles. You run the technical round, or our CTO runs it on your behalf, to your criteria. The decision is fully yours.
Flexible long-term setup
Our customers enjoy complete roadmap flexibility. They restructure their teams as demands shift, with a contractually defined buyout right available from day one.
Dedicated engineering team
Each engineer works full time on one product. We don't rotate people between accounts or park them on a bench. The team works inside your process: your backlog, your standups, your code review.
Transparent pricing model
The engineer's salary is open and our management fee is fixed on top of it. You always know which part of the invoice is the team and which part is us.
Full operational support
Employment, payroll, tax and legal administration, the office, hardware and licenses stay on our side. Our team lead club keeps the engineers growing, now around AI adoption, metrics and agent workflows. Your managers run engineering, not paperwork.
Security is our largest domain
75 of our engineers work on security products, more than in any other domain we staff. Two of those Orca Security and Cycode. Kernel, eBPF and low-level Rust take months to hire. We have filled those roles, and we flag yours upfront.
IP and security
How we protect your code and IP
You own the code from the moment it's written
Each engineer assigns their work product to On The Spot Development under Polish law as it's created. Your contract passes it straight to your company.
EU-compliant NDAs
Every engineer signs a confidentiality agreement before getting access to your systems.
Secure workstations
Every laptop has full-disk encryption and sits under central device management, so a lost device can be locked remotely. The Warsaw office opens with a badge only.
Your security rules apply
By default, engineers work on staging or anonymized data, and production data stays off their laptops. You grant access to your systems and revoke it at any time. When an engineer leaves, On The Spot Development closes every access on their last day.
What we work with
Core security product capabilities
Runtime security and kernel engineering
Agents that live inside customer workloads and must not slow them down. eBPF for low-overhead observation, Linux and Windows internals, container and Kubernetes runtimes, serverless environments where traditional agents are difficult or impossible to deploy. The bar is reliability, performance, low overhead, and the security visibility the product promises. Go, C++, Rust.
Detection engineering
Turning attacker behaviour into rules that fire on real activity and stay quiet otherwise: privilege escalation, container escape, living-off-the-land techniques, cloud reconnaissance. The hard part is keeping the false positive rate low enough to still read the alerts.
Application and supply chain security
Static analysis engines, scanners built for monorepos, ephemeral environments, GitOps workflows and machine-generated code. Correlating findings from many tools into one prioritised view instead of a long queue. Rust and Go for the engines, TypeScript and React for the interfaces people actually work in.
Cloud and delivery infrastructure
Read-only access through cloud provider APIs to scan configuration for exposed ports, misconfigurations and workload snapshots, plus monitoring CI/CD systems for malicious code in the pipeline.
Cryptographic and key security
Multi-party computation, key custody, hardware security module integration. Memory-safe languages are the requirement. Rust, WebAssembly.

FAQ
Frequently asked
questions
How do you handle access, NDAs and IP?
Every engineer signs an NDA and an IP assignment before they see anything of yours. The work product is yours, set out in the contract. Access is granted inside your own systems, under your access controls, and revoked by you when an engineer rolls off. We are the employer, you are the one who decides what they can reach.
Which parts of cybersecurity products have you staffed?
Cloud and runtime security, application and software supply chain security (including code and CI/CD security), email and social engineering security, and AI and agentic security.
Do you have engineers with eBPF and Linux kernel experience?
Yes. We have successfully built and scaled engineering teams with deep eBPF and Linux kernel experience. Our specialized tech recruitment pipeline allows us to quickly source, vet, and onboard senior systems and low-level Rust engineers for cybersecurity products.
Who decides which candidates get hired?
You do. We source, prescreen technically and present profiles, then you interview every candidate, or our CTO or a tech expert can run it to your criteria. Nobody joins your team without your decision, and you see the same information about each candidate that we do.
How long does hiring take for a role in cybersecurity product?
Hard-to-fill security roles take long, sometimes months, because the people who can do the work are already employed or not actively looking for a job. We give you the range for your specific role upfront.
Are the engineers dedicated to one product?
Yes. Each engineer works full-time on one customer product.
What about compliance and certifications?
Our engineers work inside the customer's own security processes: their onboarding, their access controls, their review requirements. Secure SDLC practice and OWASP guidance are the working default, and teams in Poland operate under GDPR.
Where are the engineers based?
Warsaw, Poland. Teams work from the office, remotely or in a hybrid pattern, whichever your engineering leadership prefers. Poland sits in CET, which gives a full working-day overlap with Israel and the UK and a partial one with the US East Coast.
We are in the seed stage. Is a dedicated team the right move?
Often not yet. If the product still changes shape every few weeks, or your stack gets rewritten monthly, a team in another country will spend its time waiting for direction. Senior technical leadership through our Fractional CTO engagement is usually the better first step.
Has a team you built ever been acquired?
Yes. ShardX, a crypto custody startup we staffed from 2018, was acquired by Gemini in 2021 together with the whole engineering team we had built. Eight of our customers have been through an M&A.
Can I convert to an ODC arrangement after recruitment?
Each model shifts the balance between control, speed, and cost. The custom software development page sets the models side by side, including where our own model is the wrong choice. Compare the models.
What if an engineer is not a fit?
Tell us early. We are the employer, so the search starts again on our side and you are not paying twice for the same role. The reason usually surfaces in the first month, which is why we ask for feedback.
Tell us which roles you need
Send us the roles and the part of the product they will work on. We will come back with a timeline per role and what each one costs in Poland.
