Website maintenance that protects what you have built

A website that has been launched is not a finished project. It is a digital asset that begins to age, accumulate security vulnerabilities and lose performance from the moment it goes live if it is not actively managed. Custom-developed systems, server infrastructure and the external libraries that every modern web project relies on regularly receive updates that fix security vulnerabilities, improve performance and ensure compatibility with new versions of browsers and operating systems. A site that does not receive these updates becomes an increasingly easy target for automated scans that continuously search the web for known vulnerabilities. Alongside the security aspect, an unmaintained website loses positions in search engines because Google treats speed, security and technical integrity as direct ranking factors. Prolink offers website maintenance as a continuous service that gives the owner confidence that their digital presence is technically sound, secure and optimised without needing to track the technical requirements that change continuously.

Security updates and patches

Most successful attacks on websites do not use sophisticated methods. They exploit known vulnerabilities in outdated software versions that the site owner simply did not update in time. Prolink develops websites and applications on its own CMS system, designed with control over every layer of the architecture, which means security updates are not subject to the logic of external platforms but are planned and applied according to the actual requirements of each project. Prolink monitors security update notifications for all systems it maintains and applies them through a controlled process that includes prior compatibility verification in a development environment, avoiding situations where an update breaks existing functionality. Periodic security reviews identify potential vulnerabilities in code, server configuration and access management before they become exploitable.

Speed and performance

Research consistently shows that every second of delay in page load time reduces conversion. A user who waits more than three seconds for a page to load abandons it without interaction in a large proportion of cases. Website performance is not a static quantity. It deteriorates over time if not actively optimised as content grows and the server configuration that was optimal at launch may no longer be appropriate for the current scale. Prolink monitors Core Web Vitals metrics that Google uses as a ranking factor, optimises the delivery of images and static assets, checks caching and CDN configuration and identifies performance bottlenecks that arise with content or traffic growth. The result is a site that remains fast and technically sound regardless of how much content or traffic changes relative to the moment of launch.

Security monitoring and protection

A reactive approach to security, waiting for something to go wrong and then responding, is an expensive and time-consuming solution that always unfolds at the worst possible moment. Prolink implements proactive monitoring that tracks site availability, detects unusual traffic patterns that may indicate an attack attempt, monitors file integrity to identify unauthorised changes and checks whether the domain or IP address has ended up on blacklists that affect email deliverability and SEO visibility. For sites that process user data or financial transactions, monitoring extends to SSL certificate validity, tracking unauthorised login attempts and detecting database injection attempts. The goal of monitoring is not only fast incident response. It is the detection of early signals that allow intervention before a problem becomes visible to users or causes measurable business damage.

Content updates

A website with outdated content sends a distorted message about the business it represents. Contact details that have changed, services that are no longer offered, prices that do not match actual prices, or news whose most recent entry is a year old, all of this undermines visitor trust and directly affects conversion. Prolink handles content updates that the owner does not have the time or technical knowledge to carry out, from text changes and adding new pages to updating galleries, blog posts and technical elements such as meta tags and structured data. Content updates are not merely an administrative task. They are part of an SEO strategy because fresh and relevant content is rewarded by Google with visibility that directly affects organic traffic.

Support and SLA

One of the most important aspects of a maintenance agreement is defining what happens when something goes wrong, how quickly someone will respond, how communication will take place and what the priorities are in the case of different types of incidents. Prolink builds maintenance agreements around clearly defined SLA parameters that specify response times for critical incidents such as site outages, security breaches or data loss, as well as deadlines for less urgent requests such as content changes and minor technical corrections. A client with agreed support is not dependent on the agency's availability at the moment something is needed. They have a guaranteed level of service that is documented and measurable, which is particularly important for businesses whose operations depend on website availability.

Maintenance plans

Why clients choose Prolink for long-term website maintenance

The relationship between a website owner and the agency that developed and maintains it should not be a series of one-off interventions but a continuous collaboration in which the agency understands the context, history and objectives of the client's digital presence. Prolink has built long-term relationships with clients through a model in which development and maintenance are not separate projects but parts of the same continuous process. This means that the person responding to an incident is not someone seeing the site for the first time. It is someone who knows its architecture, change history and the specifics relevant to a fast and accurate intervention. For international clients, Prolink offers the practical advantages of an EU-based maintenance partner, with communication in English and German, Central European timezone and the ability to arrange an in-person meeting when the situation requires it. If your website currently has no maintenance agreement or you are not satisfied with the level of support you are receiving, the Prolink team is available for a consultation with no obligation.

Website maintenance frequently asked questions

What is included in the maintenance service?

The maintenance Prolink provides covers security updates for the system and infrastructure, site availability monitoring, performance optimisation, SSL certificate validity checks and content updates according to the agreed plan scope. For sites developed on Prolink's own CMS system, maintenance also includes management of every layer of the architecture without dependency on external platforms or plugins that could introduce uncontrolled security vulnerabilities.

Why is maintenance important for a custom-developed site?

Custom-developed sites and applications are not exposed to the vulnerabilities typical of mass-market platforms, but they still require regular monitoring of security threats, server infrastructure updates and performance optimisation that naturally deteriorates over time as content and traffic grow. A site that is not maintained becomes technical debt that is more expensive to fix than to maintain continuously.

What happens if the site goes down?

Prolink monitoring detects availability outages and triggers intervention procedures without waiting for the client or a site visitor to notice the problem. Clients with agreed maintenance have defined SLA parameters that specify guaranteed response times for critical incidents, which means a site outage is not a situation where the owner waits for the agency but a situation where the agency is already responding.

Can Prolink take over maintenance of a site it did not develop?

Yes, following a prior technical analysis that establishes the state of the system, its architecture and any technical debt that needs to be addressed before the defined maintenance scope can be guaranteed. Sites developed on Prolink's own CMS system have the advantage of known context and architecture, while for sites developed elsewhere the analysis serves as the basis for a realistic assessment of scope and maintenance cost.

How much does website maintenance cost?

The price depends on system complexity, the volume of content updates and the agreed SLA. The Basic plan starts from 30 € per month and is suitable for presentation sites with minimal requirements, Standard from 80 € for more active web projects with regular content changes, and Advanced from 200 € for systems that require daily monitoring, proactive security review and guaranteed response time. A specific proposal is always defined according to the actual requirements of the project.

Is it possible to increase the maintenance scope during certain periods?

Yes, the scope can be temporarily expanded as needed, for example during periods of intensive content updates, campaign launches or high-traffic seasons. Prolink takes a flexible approach to agreed frameworks and arranges temporary expansions without the need to move to a higher plan if the increased requirement is not permanent.

How does communication work during a maintenance agreement?

Clients with agreed maintenance have a defined communication channel and guaranteed response time according to the SLA parameters of their plan. For the Advanced plan, Prolink also delivers a monthly site status report that includes a review of completed activities, security checks and performance metrics, giving the owner transparent visibility into the technical state of their digital presence without needing to track technical details themselves.
