Website maintenance - Security, performance and peace of mind
An unmaintained website is an open target. Outdated plugins, uncorrected security flaws, non-existent backups – the consequences of a lack of maintenance range from hacking to the total loss of data, to a drop in Google positions due to degraded performance.
JSEM Production provides technical maintenance to keep your site fast, secure and indexed – while you concentrate on your business.
What happens to an unmaintained WordPress site
WordPress powers 43% of the world’s websites. This is its strength – and its main vulnerability. Every plugin, every theme, every version of WordPress regularly releases security updates to correct vulnerabilities discovered by hackers. A site that fails to make these updates gradually becomes an identified target in the databases of automated attack bots.
The concrete consequences of a non-maintained site :
– Hacking and malicious code injection – your site redirects visitors to fraudulent pages without your knowledge.
– Google delisting – a site flagged as dangerous is removed from search results within 24 hours. Data loss – without a recent backup, restoration is impossible.
– Degraded loading times – obsolete plugins progressively slow down performance.
Our website maintenance services
WordPress maintenance
Our WordPress maintenance service covers all the recurring technical interventions required to keep your site running smoothly.
Interventions included every month: WordPress core update, update of all active plugins, theme update, post-update compatibility check, full site and database backup, antivirus scan and malware detection, 24-hour uptime monitoring, Core Web Vitals performance check, monthly intervention report.
E-commerce site maintenance
An e-commerce site that is down or hacked loses an average of 4.5% of its sales per hour of downtime.
E-commerce maintenance adds to standard interventions: verification of the purchase tunnel and payment process, control of payment gateways (Stripe, PayPal…), verification of inventory and order notifications, reinforced monitoring of intrusion attempts (online stores are priority targets), post-update mobile performance tests.
Hosting & SSL security
Your website’s hosting determines 40% of its performance. Low-cost shared hosting generates load times in excess of 3 seconds – costing you Google positions and high bounce rates.
We offer high-performance hosting on dedicated servers or VPS optimized for WordPress: server response time under 200ms, SSL certificate included and automatically renewed, integrated CDN for static assets, active DDoS protection, outsourced daily backups.

Why entrust maintenance to the agency that created your site?
A service provider who discovers your site at the time of an emergency wastes precious time understanding its architecture before intervening.
We know every line of configuration on every site we create.
In the event of a problem – hacking, crash, faulty update – our intervention time is 70% shorter than that of a new service provider.
This intimate knowledge of your site is the guarantee of truly effective maintenance,
not administrative maintenance.
Frequently asked questions about website maintenance
How often should I update WordPress?
WordPress releases major updates 3-4 times a year and security patches several times a month. As part of our contract, all updates are performed and tested weekly for compatibility.
What happens if my site is hacked?
Our monitoring detects intrusions within 24 hours. We intervene immediately to clean up the site, remove malicious code and restore a clean backup if necessary. Restoration is included in the contract.
Can I cancel my maintenance contract?
Yes, our contracts are monthly and can be terminated at any time with 30 days’ notice. No annual commitment required.
Do you work on sites you didn't create?
Yes, we take over the maintenance of existing sites after an initial technical audit which assesses the site’s condition and defines priority interventions before the monthly takeover.
What's the difference between hosting and maintenance?
Hosting refers to the server on which your site is stored. Maintenance refers to technical interventions on the site itself – updates, security, backups, performance. The two are complementary, and we offer them separately or in combination.
