Vincent Kilchherr December 5, 2025 5 min read

Discover the innovations of TYPO3 13.x and learn why an upgrade is worthwhile for your company.

Introduction

In today's digital era, the continuous updating of your web presence is of critical importance. With the release of TYPO3 13.x in 2025, an outstanding opportunity arises to optimise the performance of your website and integrate new, innovative features. In this blog post we examine the most significant changes in TYPO3 13.x and explain why it is advantageous for you to upgrade to the latest version now. TYPO3 remains a preferred CMS for companies that need stability, flexibility, and security — qualities that have been further strengthened in the new version.

The Problem

Numerous companies face the challenge of keeping their websites secure and up to date. The digital landscape is evolving rapidly, and the demands placed on websites are constantly increasing.

Security Concerns

  • The growing number of cyberattacks puts sensitive company data at risk.
  • Regular security updates are required to close vulnerabilities and ensure the integrity of your website.

Performance Issues

  • Loading times directly affect user experience and conversion rates.
  • Under heavy traffic, website stability can be compromised, leading to outages.

Outdated User Interface

  • Complex navigation makes content management more difficult and can impair your team's productivity.
  • A user-friendly interface is essential for efficient content administration and maintenance.

Compliance and Legal Requirements

  • Adherence to the GDPR and local Swiss regulations is essential for businesses.
  • Outdated systems can create difficulties in meeting new legal requirements.

The Solution

TYPO3 13.x offers comprehensive solutions to the challenges outlined above and enables you to make your website fit for the future.

1. Security Improvements

  • Integrated encryption methods effectively protect sensitive data from unauthorised access.
  • Regular security updates that can be installed automatically ensure continuous protection.

An example of implementing enhanced security features in TYPO3 13.x is the use of ext_localconf.php to make the configuration more secure:


$GLOBALS['TYPO3_CONF_VARS']['FE']['loginSecurityLevel'] = 'rsa';

In addition, you can further increase the security level using two-factor authentication, which is particularly beneficial for Swiss companies managing sensitive customer data.

2. Performance Optimisation

  • Optimised loading speed through improved caching mechanisms contributes to a better user experience.
  • Efficient resource utilisation, even under heavy traffic, ensures the stability and availability of your website.

To improve website performance, you can for example optimise the typo3temp directory and use the new cache manager:


$GLOBALS['TYPO3_CONF_VARS']['SYS']['enableCachingFramework'] = true;

Furthermore, TYPO3 13.x supports the integration of Content Delivery Networks (CDNs), which further reduces loading times for users worldwide.

3. User-Friendliness

  • The redesigned user interface offers more intuitive navigation, increasing efficiency in content management.
  • Improved content management tools make it easier for your team to update content quickly and simply.

The new user interface can be further personalised through adjustments in the Page TSconfig:


mod.web_layout.BackendLayouts {
  default {
    title = Default
    config {
      backend_layout {
        colCount = 3
        rowCount = 1
        rows {
          1 {
            columns {
              1 {
                name = Main Content
                colPos = 0
              }
            }
          }
        }
      }
    }
  }
}

These adjustments allow you to tailor the backend to the specific requirements of your company and maximise efficiency.

4. Legal Certainty and Compliance

  • TYPO3 13.x has been developed with current data protection standards and Swiss regulations in mind.
  • Support for GDPR-compliant features is built in, making it easier to comply with data protection guidelines.

Compliance with FINMA requirements is ensured through advanced encryption and security mechanisms integrated directly into the CMS.

Added Value

Upgrading to TYPO3 13.x brings numerous benefits that take your website to the next level.

  • Enhanced security through state-of-the-art encryption technologies protects your data from unauthorised access.
  • Faster loading times increase user satisfaction and improve search engine rankings.
  • Greater user-friendliness boosts your team's productivity and simplifies content management.
  • Compatibility with current GDPR requirements and Swiss regulations ensures legal certainty.
  • Integration with local services such as Twint, PostFinance, Swisscom, Cyon, and Hostpoint enables seamless transactions and services.
  • The flexibility of TYPO3 allows individual customisations to be made that are precisely tailored to your company's needs.

Practical Example

A Swiss company from the financial sector that migrated to TYPO3 13.x was able to achieve a significant reduction in its bounce rate through optimised performance and increased the average time spent on the website by 30%. The integration of local payment solutions such as Twint and PostFinance also improved the checkout process, resulting in a 20% increase in revenue.

By using the enhanced security features, the company was also able to effortlessly comply with FINMA requirements regarding data encryption. The improved compliance features ensured that all data protection requirements were met both in Switzerland and internationally, further strengthening customer trust in the brand.
