Your website works. But is it secure? Why outdated PHP versions put your business at risk

Арикт ЕООД

Many businesses use websites built five, ten or more years ago. These sites still work, present the company's products and services, receive customer enquiries and sometimes even process online orders.

At first glance, everything looks fine. The website loads, the information is available and there is no obvious cause for concern.

Yet one important question often goes unanswered.

If a website works, does that mean it is secure and reliable?

Unfortunately, that is not always the case.

Just as computers and phones need updates, websites rely on software that becomes outdated over time. When that software is left without updates, the risk of technical faults, security breaches and unexpected downtime gradually increases.

One of the most common problems with older websites is the use of unsupported PHP versions.

What is PHP and why should you care?

PHP is a programming language used to power many websites and online stores.

You do not need to understand the technology to see why it matters. Think of it as part of the engine that keeps your website running.

While everything works normally, you probably give it little thought.

Problems arise when that technology becomes outdated.

Like operating systems, PHP continues to evolve. New versions are released, known problems are fixed and security improvements are introduced.

Over time, however, older versions stop receiving regular updates.

For example, PHP 5 and PHP 7 have reached the end of official support from the PHP development team.

Websites using these versions may continue to run, but keeping them secure becomes considerably more difficult.

The greatest risk is that an outdated website can appear to be working perfectly while containing known security weaknesses.

Even current versions need attention.

In October 2026, urgent fixes were released for serious vulnerabilities affecting modern PHP versions too.

This is another reminder that website security requires ongoing care.

What are the practical risks for your business?

The consequences of a technical fault can extend well beyond a temporarily unavailable website.

Missed customer enquiries

Imagine that your website's contact form stops sending messages.

A visitor submits an enquiry, but it never reaches you. You may not even realise there is a problem.

By the time you discover it, you may already have lost potential customers.

Disrupted online sales

If you run an online store, a technical fault can interfere with orders, payments or communication with customers.

Even a brief outage at the wrong moment can result in lost sales and unhappy customers.

Security problems

Outdated software can contain known weaknesses that make attempts to gain unauthorised access easier.

Depending on the issue, your website's content, customer data or normal operation could be affected.

Unexpected costs

Problems sometimes appear after a change to the server environment or an update to another component.

If your system is no longer supported, restoring normal operation can prove more difficult and more expensive than a planned upgrade.

Why does changing the PHP version require preparation?

Many hosting services let you change the PHP version in just a few clicks.

An older website may need changes before it can work correctly with the new version.

Imagine trying to install a program developed ten years ago on a modern computer. Some of its features may no longer be compatible with the new environment.

The same situation can arise with websites.

Changing the PHP version directly can cause certain features to fail, make the administration panel inaccessible or stop the website from loading altogether.

An older website therefore needs a carefully planned upgrade.

The process usually includes an initial technical review, a backup, compatibility testing and fixes for any issues found.

The changes should be applied to the live website once these steps are complete.

The aim is to ensure that your website continues to perform every function your business depends on reliably after the upgrade.

Do you need an entirely new website?

That depends on the condition of your existing system.

This is one of the most common concerns among business website owners.

An upgrade can often be carried out while retaining the current design and content.

In many cases, the website's appearance and main features can be preserved as its underlying software is updated.

With some systems, however, the technology is so old that moving to current versions requires substantial changes.

This is particularly common with custom websites whose original developer no longer provides support, whose documentation is missing or whose software components were abandoned long ago.

In these cases, it makes sense to compare the cost of modernising the existing site with the cost of building a new solution.

The decision should follow a technical assessment that considers the website's condition and requirements alongside its age.

Sometimes a few targeted improvements can significantly extend the useful life of an existing system. In other cases, a complete replacement is the more sensible choice.

Why should you act before your website stops working?

Many businesses arrange website maintenance only when something goes wrong.

This approach can seem economical because it avoids regular costs.

When the website suddenly stops working, however, the problem usually needs urgent attention.

That can mean interrupted operations, lost customer enquiries and additional recovery costs.

An emergency also leaves little time to choose the most appropriate technical solution.

Planning the necessary changes in advance gives you more control.

It allows time for checks, backups and the selection of a suitable time for the upgrade.

Good maintenance helps you manage risks systematically and prepare for problems that may still occur.

What does professional website maintenance involve?

A website needs continued attention throughout its working life.

It is part of your company's IT infrastructure and, like other systems, requires regular care.

Professional website and online store maintenance can bring together a range of activities needed to keep your system running reliably.

These include regular updates, vulnerability checks, troubleshooting, backup management and monitoring of essential features.

Depending on the website, the service may also include measures to improve performance, stability and compatibility with newer technologies.

With an ongoing maintenance plan, these activities are organised within an agreed scope of service.

The business owner gains a technical partner who understands the system, monitors its condition and can plan the changes it needs.

This makes costs more predictable and reduces reliance on urgent, unplanned interventions.

Website monitoring and early problem detection

Imagine that your website stops working on a Saturday evening.

If nobody is monitoring it, you might only discover the problem on Monday morning, or when an unhappy customer calls.

Monitoring helps you detect these problems sooner.

Website monitoring uses automated checks to track the condition of a website and identify certain problems promptly.

A dedicated system can check regularly whether the website is available, responds normally and shows particular technical errors.

It can also track other indicators, such as the validity of the certificate used for a secure connection or the server's response time.

When a problem is detected, the responsible technical team receives an automatic notification and can act in line with the agreed service terms.

Monitoring has its limits. It cannot prevent every fault, and a basic check that a website loads will miss some errors.

For example, checking that contact forms and the online ordering process work correctly may require additional, specialised tests.

Monitoring is therefore most effective as part of a coordinated technical maintenance service.

You can then have a system that alerts the responsible specialists promptly when it detects a problem.

Why might a backup be insufficient?

When a technical problem occurs, the first question is often whether a backup is available to restore the website.

There is another equally important question. When did someone last check that the backup could actually be used?

Having a backup does not guarantee a successful recovery.

The backup may be incomplete, corrupted or too old.

For online stores, the situation is especially sensitive because restoring an older backup can mean losing recent orders.

Reliable maintenance therefore includes checking the condition of backups and testing recovery periodically, alongside creating the backups themselves.

Five questions every business website owner should ask

You do not need programming knowledge to assess whether your website's technical maintenance is well organised.

Consider the following questions.

1. When was your website's software last updated?
2. Do you know whether the technologies it uses are still supported?
3. Who checks that contact forms, orders and other essential features work correctly?
4. Do you have a tested backup and a recovery plan?
5. Who will notice and respond if the website goes down outside business hours?

If you cannot answer these questions clearly, a technical review can help you understand the website's condition.

It is a practical starting point for deciding what attention the site needs.
