DevSecOps: where to start if development is already underway

DevSecOps is needed not so that information security becomes a brake on development, but so that critical risks are detected earlier, cheaper and more manageable.

Safe development as a cycle

Mature secure development begins not with the purchase of a scanner, but with a lifecycle model: requirements, architecture, threat modeling, development, code review, SAST/SCA, testing, DAST, infrastructure testing, release, monitoring and incident analysis. Each stage has its own control, owner and acceptance criteria.

Plan

Requirements and risks

System classification, data, roles, threat model, regulatory requirements and acceptance criteria.

Build

Development

Secure coding, review, secrets, dependencies, containers, IaC and automatic checks in the pipeline.

Test

Examination

SAST, SCA, DAST, API security, access rights tests, load and defect handling.

Run

Operation

Monitoring, VM, patching, incidents, lessons learned and improvement of development rules.

How to start without overload

Critical systems

Select 3-5 systems where there is personal data, money, client access, API or high damage from downtime.

Minimum pipeline

Add SCA, secrets, basic SAST, and blocking rules only for truly critical defects.

Architectural solutions

Threat modeling on key data streams often provides more value than bulk scanning indiscriminately.

Metrics

See mean time to remediate, defect repeatability, repository coverage, and post-release defects.

Let's discuss your environment

Describe the task, current systems, constraints, and expected results. We will offer a practical first step: diagnostics, pilot, audit, roadmap or project team.
