Secure Software Development

Security that starts at the first line of code, not after launch. We build it into design, development, testing and release, with AI helping our engineers catch problems earlier.

Why teams choose Sosene for secure software development

Secure software development starts early, because most security problems enter the code during the build. They are also cheapest to fix there. So we make security part of every stage, with automated checks in the pipeline and reviews by engineers who know what to look for. In addition, AI helps us spot risky code early.

Security from the design stage

We find threats and sensitive data before building, so we design protection in instead of patching it on later.

Checks in every build

Code scanning, dependency checks and secret detection also run automatically in the CI/CD pipeline.

Human review where it counts

AI flags suspicious patterns. Then an experienced engineer reviews login, payments and data handling.

Evidence you can show

We document findings, fixes and decisions. As a result, customer questionnaires and audits get easier.

Security that moves at the speed of your releases

Security reviews should not hold every release for weeks. With DevSecOps, most checks run automatically on each change, so people can focus on the risks that matter. As a result, your team keeps shipping, and each version is safer than the one before.

Secure software development services we offer

Our secure software development services cover new products and apps already in production. For example, we test against the OWASP Top 10 risks.

Threat modelling

A structured look at what could go wrong in your application, and the controls to prevent it.

Secure code review

Manual and AI-assisted review of your code for common flaws and risky logic.

DevSecOps pipelines

Automated security testing, dependency scanning and secret detection added to your build process.

Application security testing

We test web apps, mobile apps and APIs against common attacks, and we explain each fix clearly.

Vulnerability remediation

We fix what testing finds, in our code or in yours. Then we verify each fix.

Secure coding training

Practical sessions for your developers, based on the issues we actually find in your code.

Three ways to work with an AI-driven team

The commercial model changes with your goals. The way the team works does not.

AI-assisted full outsourcing

Project-based delivery

We take ownership of the whole project, from discovery and solution design through build, testing, deployment and launch. Delivery runs under agile governance, with AI applied to requirement analysis, development support, QA preparation, documentation and reporting. A named engineer signs off on every output.

AI-driven dedicated agile team

A standing team with committed sprint outcomes

A dedicated agile team aligned to your roadmap and your backlog. Sprint deliverables are planned and agreed with you against your priorities, backlog readiness and team capacity. The team applies AI across the lifecycle, from requirement analysis and user stories to coding, QA, documentation and sprint reporting.

AI-enabled staff augmentation

Specialists under your direction

Technology professionals who join your in-house team and work under your direction, process and management. They bring the technical depth you asked for plus AI-assisted working methods, which shows up as faster development, better documentation and stronger test preparation.

How security fits into our delivery

In secure software development, we add security work to each stage of the lifecycle, and we scale it to your risk.

01 Requirements

Security and privacy needs, agreed next to the functional ones.

02 Design

Threat modelling and secure architecture choices for data, access and integrations.

03 Development

Secure coding standards, AI-assisted checks and peer review on sensitive code.

04 Pipeline

Automated scans for code, dependencies, containers and leaked secrets on every change.

05 Testing

Security testing before major releases, with findings tracked to closure.

06 Operations

Patches, alerts on new flaws in the libraries you use, and regular reviews.

What keeps delivery predictable

Speed only counts if the result holds up. These practices sit behind every engagement, whichever model you choose.

Project foundation

  • Scope defined together, in writing
  • A team composed for the work, not the average
  • Roadmap and milestones agreed up front

Cost control

  • A transparent estimation method
  • Build order driven by business value
  • Savings that never come out of quality

Collaboration

  • One communication framework, not five
  • Roles and responsibilities named per task
  • Regular alignment with your stakeholders

Risk management

  • Risks identified before the build starts
  • Continuous monitoring through the lifecycle
  • A named owner for each mitigation

Change management

  • A single route for change requests
  • Impact assessed before anything is committed
  • Approved changes scheduled without drama

Quality assurance

  • Success metrics agreed at the start
  • KPI reporting you can check yourself
  • Improvement cycles between releases

Knowledge transfer

  • Structured documentation, kept current with AI
  • Handover built into the plan, not bolted on
  • Technical specifications written to be used

After launch

  • Warranty coverage on what we deliver
  • Maintenance options that match your load
  • The same team available for the next phase

Frequently asked questions

It means adding security checks to the same automated pipeline that builds and deploys your software. As a result, we catch problems with every change instead of in an occasional audit.

Yes. We review the code and configuration, report findings by severity, and can fix them or support your team while they do.

This page is about the software itself: how we design, code and release it. In contrast, Cybersecurity Services covers the wider environment, such as endpoints, networks and managed security.

Less than fixing incidents does. Automated checks add only minutes to a build. In addition, catching issues early avoids costly rework after release.

How secure development engagements are priced

Two commercial models, and one honest answer about numbers.

Fixed priceTime and materialsHow we reach a number
One price agreed in the contract. It fits feasibility studies, proofs of concept and small pieces of work where the requirements are settled and unlikely to move.You pay for the hours worked each month, with an optional cap that sets a ceiling for budget control. This suits advisory work, business analysis, architecture and planning, agile delivery, and modernising software you already run.Every estimate starts with a short discovery call. You get a written proposal with named engineers, a delivery timeline and a price before anything is committed. Cost depends on scope, integrations and compliance requirements, so we quote per project rather than from a list.
