Security Patching and Updates That Do Not Break Your App
Outdated servers, frameworks and libraries are the easiest way into your application. We find what is vulnerable, prioritise by real risk and update it safely, every month.
What Are Security Patching and Update Services?
Security patching and update services keep every layer of a live application up to date with security fixes: the operating system, web server, runtime, database, framework and the open-source libraries the code depends on. The work includes finding vulnerabilities, deciding what to fix first, testing updates, deploying them safely and confirming the fix, on a regular schedule and within agreed timeframes.
Codersarts provides patch management and dependency update services for web applications, APIs, SaaS products and the servers they run on. We find what is outdated or vulnerable, prioritise by real risk, test every update before release and roll back quickly if anything misbehaves, so your app stays secure without breaking.
Most successful attacks use vulnerabilities that already had a fix available. Patching on time is one of the most effective security controls a business can have.

Why Unpatched Software Is a Serious Risk
Vulnerabilities are published constantly. New security issues are disclosed in popular open-source packages every week, and public advisories show attackers exactly what to look for
Attackers scan automatically. Bots search the internet for servers and applications running known vulnerable versions within days, sometimes hours, of disclosure
Modern apps have hundreds of dependencies. A typical JavaScript or Python application pulls in hundreds of packages indirectly, each with its own update cycle
Old versions lose support. Runtimes, frameworks and databases stop receiving security fixes after their end-of-life date
Updates pile up. Skipping small updates for months turns routine maintenance into a risky, multi-version upgrade
Customers and auditors ask. Security questionnaires, cyber insurance and compliance frameworks such as SOC 2, ISO 27001 and PCI DSS expect a documented patching process
What We Patch, Layer by Layer
Layer | Examples | How it is updated |
|---|---|---|
Operating system | Ubuntu, Debian, Amazon Linux, Alpine | Automatic security updates plus scheduled reboots where kernels change |
Web server and proxy | Nginx, Apache, Caddy | Package updates tested against your configuration |
Runtime | Node.js, Python, PHP, Java, Go | Planned upgrades between supported release lines |
Database | PostgreSQL, MySQL, MongoDB, Redis | Minor updates in maintenance windows, major upgrades as planned projects |
Framework | Express, NestJS, Next.js, React, Django, Laravel, Rails | Version updates with code changes where the framework requires them |
Libraries | npm, pip, Composer, Maven and Go modules | Dependency updates grouped, tested and released regularly |
Containers | Docker base images | Rebuilt on current base images and rescanned |
Third-party SDKs | Payment, email, login and AI provider SDKs | Updated before providers retire old versions |
How We Prioritise Vulnerabilities
Not every vulnerability is equally dangerous. Patching everything immediately is not realistic, and treating everything as low priority is unsafe. We rank each issue by four factors:
Severity. The published severity score, usually from the Common Vulnerability Scoring System (CVSS).
Exploitation. Whether the vulnerability is known to be exploited in the wild, for example if it appears in the US Cybersecurity and Infrastructure Security Agency's Known Exploited Vulnerabilities (KEV) catalogue.
Exposure. Whether the vulnerable component is reachable from the internet or only used internally or during development.
Impact. What an attacker could reach: customer data, payments, administrative access or nothing sensitive.
Government guidance is moving in the same direction. In June 2026, CISA replaced its earlier fixed-deadline approach for US federal agencies with a risk-based directive in which the most exposed, actively exploited vulnerabilities must be fixed within days, and lower-risk issues on longer schedules.
Patching Timeframes
These are the default targets we agree with clients. They can be tightened for regulated or high-risk applications.
Priority | Typical example | Target to fix or mitigate |
|---|---|---|
Emergency | Actively exploited and reachable from the internet | Mitigation within 1 business day, fix as soon as a safe update exists |
High | Critical or high severity in a component that is exposed | Within 14 days |
Medium | Medium severity, or high severity in an internal component | Within 30 days |
Low | Low severity or development-only dependencies | In the next scheduled update cycle |
When no fix exists yet, we apply a mitigation, such as a configuration change, a firewall or web application firewall rule, or disabling an affected feature, and track the issue until a patch is released.
How We Update Without Breaking Your App
Fear of breaking things is the main reason updates are postponed. Our process removes most of that risk:
Scan. Automated tools such as GitHub Dependabot, npm audit, pip-audit, OSV-Scanner or Trivy report outdated and vulnerable components.
Group. Related updates are grouped so each release is small and easy to review.
Read the changelog. For major versions, we check breaking changes and adjust the code.
Test. Automated tests run on every update. Where tests are missing, we add checks for the most important user flows.
Stage. Updates are deployed to a staging environment first and checked.
Release. Updates go to production through your deployment process, at a planned time.
Watch and roll back. Error rates and performance are monitored after release, and the previous version is restored quickly if needed.
Record. Each change is recorded in version control and in the monthly report.
Operating System and Server Patching
Unattended security updates for operating system packages, with change logs reviewed
Scheduled reboots for kernel updates, timed to avoid business hours where possible
Old and unused packages removed to reduce the attack surface
Servers on end-of-life operating system versions upgraded or rebuilt
SSH, firewall and service configuration checked after each change
Dependency Updates for Application Code
Most application vulnerabilities live in third-party libraries rather than in your own code. We keep dependencies current with:
Lock files committed and maintained, so every environment installs the same versions
Regular minor updates so major upgrades never pile up
Planned major upgrades, such as moving to a new framework or runtime release line, scheduled before end of life
Replacement of abandoned packages that no longer receive security fixes
Removal of unused dependencies, which reduces both risk and build times
Clearing a Patch Backlog
Many applications we take over have months or years of skipped updates. Rather than attempting everything at once, we:
Fix actively exploited and internet-facing vulnerabilities first.
Bring the runtime and framework onto supported versions in planned steps.
Update remaining libraries in small, tested batches.
Switch to regular monthly updates so the backlog never returns.
If your app was handed over by a previous developer, this work is part of a Take Over Existing App engagement.
Common Reasons Updates Get Skipped, and How We Solve Them
Reason | What happens | How we solve it |
|---|---|---|
No tests, so nobody knows what might break | Updates are postponed indefinitely | We add checks for the most important user flows before updating |
One large framework jump instead of many small steps | The upgrade becomes a project nobody has time for | We move through supported versions in planned steps |
The original developer has left | Nobody understands the code well enough to update it | We review and document the app first, then update |
Updates require downtime | They are delayed to a quiet time that never comes | We use rolling or blue-green releases where possible, or agree a short window |
Too many alerts from scanners | Real risks are lost among low-priority warnings | We prioritise by exploitation, exposure and impact, and suppress noise with documented reasons |
Supply Chain Security
Attackers also target the software supply chain: publishing malicious packages with names similar to popular ones, taking over abandoned packages or compromising build systems. Patching alone does not stop these attacks, so we add basic supply chain controls:
Lock files and exact versions so builds cannot silently pull new code
Review of new dependencies before they are added
Alerts on packages that become deprecated, abandoned or flagged as malicious
Least-privilege tokens for build and deployment pipelines
A software bill of materials (SBOM) for applications that need one for customers or compliance
Patching vs Security Audits
Service | What it does | When you need it |
|---|---|---|
Security patching and updates | Ongoing, scheduled work to keep known vulnerabilities fixed | Every month, for every live application |
Security audit | A one-time, in-depth review of code, configuration and design for weaknesses that patching does not catch | Before launch, funding, enterprise deals or after major changes |
The two complement each other. For an in-depth review, see our Web Application Security Audit, or the AI-Generated Code Audit for apps built with AI coding tools.
End-of-Life Tracking
Every runtime, framework, database and operating system has a published support end date. We keep a list of the versions your application uses and their end-of-life dates, and plan upgrades well before support ends, so a version never quietly stops receiving security fixes. Upcoming dates appear in every monthly report with a recommended upgrade window.
Evidence for Compliance and Customers
Many companies need to prove that patching happens, not only do it. Every month you receive:
A list of vulnerabilities found, with severity and status
What was fixed, when and in which release
Any risks accepted, with the reason and review date
Supported and end-of-life versions across your stack
This evidence supports security questionnaires, cyber insurance renewals and audits for frameworks such as SOC 2 and ISO 27001.

Frequently Asked Questions
What is patch management?
Patch management is the ongoing process of finding, prioritising, testing and installing security updates for operating systems, runtimes, databases, frameworks and libraries.
How quickly should critical vulnerabilities be patched?
Actively exploited vulnerabilities on internet-facing systems should be mitigated within a day and fixed as soon as a safe update exists. Other high-severity issues are typically fixed within 14 days.
Will updates break my application?
Updates can introduce breaking changes, which is why we test every update, release through staging and keep a fast rollback ready.
Do you update npm and Python dependencies?
Yes. We maintain npm, pip, Composer and other dependencies with automated scanning, grouped updates and testing.
How much does security patching cost?
Ongoing patching is included in Managed Run, starting at $1,000 per month. Backlog clean-up is estimated after review and charged at $50 per hour with your approval.
What if no patch exists yet?
We apply a mitigation, such as a configuration change or firewall rule, and track the issue until the vendor releases a fix.
Is patching the same as a security audit?
No. Patching fixes known vulnerabilities on an ongoing basis. A security audit looks deeper for design and code weaknesses that updates do not address.
Can you provide evidence for SOC 2 or ISO 27001?
Yes. The monthly report records vulnerabilities, fixes, accepted risks and version status, which supports audit evidence.
