From HTTPS to machine trust: the rise of mTLS client certificates
In recent years, we have seen something interesting happen: the digital certificate, which many associated only with HTTPS, is becoming increasingly central in modern architectures. This is because it is undeniable that machines communicate more than humans do. And when they communicate with each other—via APIs, microservices, cloud integrations, or exchanges between trusted platforms—the question is no longer just “is the channel encrypted?”, but above all: who is making the call? what is its identity? This is where mutual TLS, or mTLS, comes into play. In “standard” TLS, the server presents its certificate, and the client trusts it (if everything checks out). With mTLS, an additional step is introduced: the client also authenticates itself using an X.509 certificate. So both parties prove their cryptographic identity. The result? We are no longer just protecting a communication—we are building a verifiable trust relationship.
Actalis SSL certificates for IP addresses: practical, compliant, ready to use
If your infrastructure doesn’t use DNS, an SSL certificate for an IP address can be the ideal way to enable HTTPS and verify server identity. Actalis now offers this capability as part of its Organisation Validated (OV) SSL certificate range.
NIS2: what changes for European companies and how to comply with encryption requirements
The NIS2 Directive (EU 2022/2555) was introduced to strengthen cybersecurity across the European Union. It establishes stricter security standards and clearer responsibilities for organisations in key sectors, requiring them to take proactive steps to prevent cyber incidents.
Cloud Security: why digital certificates are essential for protecting cloud applications
In today’s cloud-driven world, security is a top priority for businesses and institutions alike. Digital certificates and advanced encryption have become fundamental to protecting cloud-based applications and data
Actalis on the Future of Cybersecurity: Certificates, Identity, and Digital Trust
Cyberattacks are rising. Compliance rules are tightening. And yet most public institutions and businesses still rely on SSL certificates that validate only domain ownership. According to Francesco Basso, Head of SSL and Security Business Line, Actalis S.p.A. (Aruba Group), “when a certificate proves only that someone owns a web address—but not who they are or whether they’re legitimate—we create a false sense of trust.”
