FAQ
Straight answers about what CodeSec does and how we work.
CodeSec is a cybersecurity, DevSecOps and software engineering company. Our team builds websites, SaaS platforms, APIs, browser extensions and mobile apps, secures applications and infrastructure, deploys them to reliable cloud or VPS environments, and monitors them once they are live.
Yes — that is the core of what we do. Our engineers build the application while our security team reviews it throughout the project, covering authentication, data handling, APIs and infrastructure. Security becomes part of the build instead of a fix after launch.
Websites and web applications, SaaS products, APIs and backend services, Chrome extensions, and Android and iOS apps. We typically work with modern stacks such as Next.js, React, Node.js and Python, deployed with Docker on cloud or VPS infrastructure.
A security scan is an automated check of your website or application from the outside. The CodeSec scanner reviews areas such as SSL/TLS configuration, security headers, DNS, detected technologies and common misconfigurations, then gives you a security score and a report explaining what to fix.
Yes. We usually start with a scan and a review of your current application and infrastructure, confirm which issues are real, prioritise them by risk, and then help implement the fixes — whether your team or ours wrote the original code.
Yes. Our engineers set up and manage cloud and VPS environments, including Docker, CI/CD pipelines with GitHub Actions, Cloudflare, server hardening and backups, so deployments are secure and repeatable.
Yes. We can set up continuous monitoring for uptime, security posture and infrastructure health, so problems such as a failing service or a new configuration risk are noticed early rather than reported by your users.
A scan is automated: it quickly checks for known issues and misconfigurations and is worth running regularly. An assessment is carried out by our security team: we look at how your application and infrastructure actually work, verify findings, review areas automated tools cannot judge — such as access control and business logic — and give you prioritised recommendations.
