cert-manager is an open-source tool designed to automate the management and issuance of TLS/SSL certificates in Kubernetes environments. Developed originally by Jetstack (a Kubernetes consultancy company acquired by Venafi), cert-manager simplifies and automates certificate provisioning through integrations with Let's Encrypt, HashiCorp Vault, and other certificate authorities.
The tool is widely adopted across cloud-native and DevOps communities to ensure secure communication within Kubernetes clusters. It supports a range of issuers and certificate renewal strategies, offering enterprises a scalable and automated way to manage public key infrastructure (PKI).
cert-manager is part of the Cloud Native Computing Foundation (CNCF), highlighting its importance and credibility in the Kubernetes ecosystem.
The cert-manager logo has remained largely consistent since its inception, keeping a maritime-inspired identity that emphasizes stability, trust, and control. The branding reflects core values tied to security and infrastructure reliability — essential in the context of digital certificate management.
The visual identity has matured along with the project, balancing open-source approachability with enterprise-level trust.
The logo features two components: a symbolic badge icon and a wordmark.
The badge-style icon is circular with wavy edges, resembling a wax seal or maritime emblem, which traditionally signifies authenticity and authority.
At the center is an anchor surrounded by horizontal wave lines, symbolizing stability, trust, and control — all essential qualities of a certificate management system.
The word “CERT” appears at the top and “MANAGER” at the bottom, forming a cohesive circular text that reinforces the name while completing the seal motif.
The anchor also visually suggests the idea of “anchoring trust,” a concept fundamental to TLS/SSL certificates, which establish secure, verifiable connections between machines.
The accompanying wordmark uses a clean, geometric sans-serif font in all lowercase: cert-manager.
The typeface is bold, friendly, and highly legible, contributing to the open-source, community-focused identity of the project.
The use of lowercase letters creates a sense of accessibility and approachability, which is in line with many developer-centric tools.
The typographic design strikes a balance between modernity and technical clarity, making it ideal for documentation, terminals, and web interfaces.
The logo uses a vivid blue color (#0077FF) that is consistent across both the icon and the text.
Blue is a strategic choice in cybersecurity and software branding. It conveys trust, security, and professionalism, which are essential to the cert-manager’s function.
The monochromatic approach ensures consistency and high adaptability across light and dark backgrounds, both in development environments and corporate presentations.
cert-manager’s logo is a combination mark — a mix of a symbol (badge) and typographic wordmark. This type of logo offers flexibility: the badge alone can be used as a favicon, CLI tool icon, or social media avatar, while the full version works perfectly for documentation headers and presentations.
The badge’s seal-like form also implies a stamp of authenticity, echoing the purpose of digital certificates as cryptographic validators of identity.
The cert-manager logo is crafted to be clean and scalable, fitting perfectly into modern DevOps interfaces, websites, and Kubernetes dashboards. You can download the logo in various high-quality formats including SVG, PDF, AI, and transparent PNG from logowik.com, ideal for both development and promotional use.
The cert-manager logo is a powerful representation of its purpose: managing and securing digital trust in cloud-native environments. With its maritime-inspired design, authoritative seal layout, and strong color palette, the logo symbolizes reliability, control, and automation.
Its design successfully blends developer-friendliness with enterprise-grade confidence, making it recognizable and memorable in the rapidly evolving Kubernetes and DevSecOps landscape. Whether deployed at scale or used by independent developers, cert-manager’s visual identity stands as a symbol of modern, secure infrastructure management.
