Application Maintenance & Web Technical Expertise
Sooweb handles the application maintenance of your web projects — updates, security patches, optimisations — so you can focus on your business without ever fearing a service interruption.
Expertise covering your entire web environment
Our team masters the technologies that power 90 % of SME and agency web infrastructures. The application maintenance we provide is built on an in-depth knowledge of every component of your stack, from the server right up to the application layer.
Server infrastructure
Our technicians work daily on Linux environments (Debian, Ubuntu Server, CentOS) hosting high-traffic websites. We configure and maintain Nginx and Apache web servers in both directions — reverse proxying, security headers, SSL/TLS certificate management, rewrite rules. Application performance always starts with a properly sized and optimised server.
For the database layer, we manage MySQL and MariaDB: slow query analysis, index optimisation, unused table cleanup, automated backups and regular restoration tests. Our application maintenance monitoring systematically includes the database side, which is often the source of undetected performance degradation.
Application layer
On the application runtime side, we work with PHP (versions 7.4 to 8.3) and Node.js. Managing PHP version upgrades — often a source of regressions — is an integral part of our application maintenance contracts. We anticipate incompatibilities, test in a pre-production environment and deploy without service interruption.
Node.js projects benefit from npm dependency tracking (npm audit), process monitoring via PM2 and a continuous deployment pipeline if the project requires it. Our engineers know the subtleties of each runtime environment and operate with full autonomy.
Mastered technologies
Complete application maintenance — corrective and evolutionary
The Third-Party Application Maintenance (TMA) we offer covers the entire lifecycle of your application: we update, fix, secure and improve your digital tools on a defined schedule or on demand.
CMS & plugin updates
We schedule and apply updates to your CMS (WordPress, Drupal, PrestaShop) and all its extensions. Each update is carried out after testing in a staging environment to avoid any regression in production. Regular application maintenance is the first line of defence against known vulnerabilities.
Security patches & patching
Security vulnerabilities show no mercy. As soon as a CVE (Common Vulnerabilities and Exposures) is published for a technology you use, our team analyses the impact, prepares the fix and deploys it according to the criticality deadline. We also apply recommended hardening measures (disabling dangerous PHP functions, securing HTTP headers, etc.).
Database optimisation
A poorly maintained database is often the main source of unexplained slowdowns. We perform regular audits: slow query log analysis, index optimisation, cleanup of obsolete revisions and transients (WordPress), re-indexing of MyISAM/InnoDB tables and archiving of historical data. The result: improved response times and a significant reduction in server load.
Corrective maintenance
A form that no longer sends, a blank page after an update, a regression after a deployment: we diagnose and fix functional anomalies in your applications. Our corrective application maintenance process includes an incident report detailing the root cause and associated preventive actions.
Backups & restoration
A backup strategy without restoration testing is worthless. We set up automated daily backups (files + database) stored on an isolated third-party space, and schedule periodic test restorations to validate data integrity. In the event of an incident, the RPO (Recovery Point Objective) and RTO (Recovery Time Objective) are defined contractually.
Evolutionary maintenance (TMA)
Beyond fixes, evolutionary application maintenance evolves your tools to meet new business needs: adding an appointment booking module, integrating a third-party API, migrating to a major CMS version or partially redesigning a critical feature. Each evolution is specified, costed and validated before development.
Level 1, 2 and 3 support — A single point of contact for all your emergencies
Our three-tier support model ensures that every issue is handled by the right expert, at the right time, without you having to manage escalation yourself. From a simple user ticket to an emergency intervention on your critical infrastructure, we cover the full spectrum.
Unlike many service providers, our application maintenance contract does not outsource level 1 to an offshore call centre. From the very first contact, you speak to a technician who knows your environment.
Entrust My MaintenanceLevel 1 — User support & tickets
Handling of routine requests, functional questions, minor anomalies. Guaranteed response in under 4 business hours via our ticket portal. Ideal for teams using your CMS on a daily basis.
Level 2 — Technical expertise & diagnostics
Escalation of complex incidents requiring in-depth investigation: server log analysis, application debugging, query optimisation, plugin conflicts. Immediate handling for blocking incidents.
Level 3 — On-call duty & emergency intervention
On-call service available for clients requiring coverage outside business hours. In the event of a site going offline, a security breach or a critical incident, our team responds within 30 minutes, 7 days a week, 24 hours a day. No outage goes unanswered.
Continuous monitoring & intelligent alerting
Reactive application maintenance is no longer enough. We implement a proactive monitoring layer that detects anomalies before they become incidents. HTTP availability, response times, CPU/RAM consumption, disk space, SSL certificate validity: every critical metric is continuously monitored, with alert thresholds defined according to your risk profile.
Availability checks every 60 seconds from multiple geographic points of presence to eliminate false positives and guarantee a reliable availability SLA.
Instant multi-channel alerts (email, SMS, Slack, webhook) as soon as a threshold is crossed, with criticality-based prioritisation to avoid alert fatigue.
Detailed monthly reports including measured availability rate, incidents with timeline, corrective actions applied and optimisation recommendations for the following month.
Trend analysis to anticipate saturation (full disk, rapidly growing database) and plan infrastructure upgrades before an incident occurs.
What sets our approach to application maintenance apart
Many agencies offer web maintenance. Here is why CIOs and SME managers choose Sooweb to outsource their TMA.
Dedicated team
A designated technician knows your environment inside out. No random rotation of staff.
Full transparency
Every action taken is documented in your client space. No ghost interventions, no hours billed without proof.
Controlled costs
Predictable monthly flat rates, with no surprises. You know exactly what you are paying, and why, every month.
Proven responsiveness
Our SLAs are contractual and measured. In the event of a breach, you are refunded for the relevant portion of the flat rate.
"Since Sooweb took over the application maintenance of our PrestaShop store, our load times have been cut in half and we have had no service interruptions whatsoever. The monthly report gives us complete visibility into what is being done. A trusted partnership."
