Security patching, software upgrades, and server hardening that keep your website, app, and business systems safe, without disrupting your business.
Most security incidents at small and medium businesses don't start with a sophisticated attack. They start with something ordinary: an outdated plugin, an unsupported framework, a server nobody has updated in years, or an admin account that should have been closed. Automated bots scan the internet for exactly these weaknesses every day.
DEVR Tech helps businesses in Singapore and Malaysia close those gaps. We keep your systems patched and up to date, upgrade components before they reach end of life, harden servers and cloud settings, and make sure your backups actually work.
Because we're software developers, we don't stop at a list of problems — we fix them in your code and configuration, then test that everything still works. We work on systems we built and on ones we didn't.
We practise what we recommend: our own website runs on HTTPS with HSTS, a strict Content Security Policy, and other security headers, which you can check with any header-scanning tool.
Regular updates to frameworks, libraries, plugins, and server software to close known vulnerabilities.
Planned upgrades from unsupported versions to current ones, tested so nothing breaks.
Locked-down servers and cloud settings: least-privilege access, firewalls, and secure configuration.
Valid certificates, HTTPS everywhere, and headers like HSTS and a Content Security Policy.
Unused accounts and services removed, and two-factor authentication turned on for admins.
Automated off-site backups, tested restores, and uptime monitoring so problems are caught early.
Patching keeps a sound system safe: security updates and minor version bumps, applied regularly. Upgrading moves core components — a language version, framework, or database — off versions that no longer receive security fixes. Small, regular upgrades cost far less than one giant jump later.
When a system is so far behind that upgrading costs nearly as much as starting over, a rebuild can be the better investment, and a chance to fix the workflow as well as the technology. We'll tell you which option fits after reviewing your system.

We map what's running, the versions involved, and who has access.
A prioritised list of fixes and upgrades, most urgent first, with the effort for each.
We apply patches, upgrades, and hardening, testing that everything still works.
Ongoing updates, backups, and monitoring, so your systems stay current.
Cost depends on the size and age of your system, how far behind it is, and whether you need a one-off clean-up or ongoing maintenance. Tell us what you run and we'll send a free quote within 24 hours.
Not at the moment. Penetration testing services require a licence from Singapore's Cybersecurity Services Regulation Office (CSRO) or Malaysia's National Cyber Security Agency (NACSA). Our service focuses on patching, upgrades, hardening, and backups — and if you have a report from a licensed penetration test, we can fix the issues it finds.
Yes. We start by reviewing what's running and how it's deployed, then propose a plan. We'll need access to the code, hosting, and admin accounts.
Critical security fixes should be applied as soon as practical after they're released. For everything else, a regular monthly or quarterly cycle suits most businesses, with larger upgrades planned ahead of end-of-life dates.
Updates can occasionally change behaviour, which is why we take a backup first, test before and after applying changes, and schedule them for quiet periods.
