Written by Shan Chin DingSeptember 24, 2025In today’s digital environment, making sure authentication and authorisation are handled securely is essential for any modern application. Two major standards that help solve these challenges are OAuth 2.0 (Open Authorisation) and OpenID Connect (OIDC). Although they are often discussed together and may seem similar at first glance, it’s important, especially for developers, system architects, and security teams, to understand the
Written by Steven CheahSeptember 4, 2025The public key infrastructure (PKI) is a widely accepted standard in the security industry and the foundation of trust and secure digital communication across various applications, from websites’ SSL/TLS and document signing to secure email and remote work.

Continuous monitoring is a highly useful strategy, monitoring certificates’ health and security before
Written by Kimchav SovJune 12, 2025In recent years, the lifespan of certificates has been significantly shortened. Taking Apple, as an example, they have proposed reducing certificate lifespans from 398 to 47 days by 2029. With this dramatic reduction in certificate lifespan, managing certificates from multiple certificate authorities (CAs) can be a hassle and time-consuming, potentially leading to system disruptions as manual processes may be insufficient and
Written by Aaron FuMay 28, 2025In the new digital age, there is a huge dependence on digital services. Organisations are forced to prioritise SSL certificate renewals to maintain secure and uninterrupted operations.
