About InsecurePlanet

Security current events explained for enterprise engineers, PKI administrators, and IT leaders.

Security current events, PKI risk, identity threats, and enterprise cybersecurity explained for the people who operate real systems.

Mission

InsecurePlanet exists to give enterprise security practitioners clear, accurate, and actionable intelligence on the threats and vulnerabilities that affect the systems they are responsible for — without the noise, vendor agenda, or sensationalism that makes most security content hard to use.

Why InsecurePlanet Exists

We live on an insecure planet. That has always been true.

The original premise of InsecurePlanet was straightforward: the more technologically advanced society becomes, the more vulnerable it becomes. Modern networks now manage and control critical infrastructure — power grids, water systems, transportation, healthcare, financial systems, and the communications infrastructure that ties everything together.

That premise has not changed. What has changed is where the most consequential security failures are happening. Today, the most damaging enterprise compromises run through identity infrastructure — Active Directory, certificate services, authentication systems — not through perimeter breaches. Ransomware operators, nation-state actors, and opportunistic attackers have all converged on the same target: the systems that control who and what is trusted inside an organization.

InsecurePlanet focuses on that intersection — the security of the infrastructure that enterprise organizations depend on to establish and enforce trust. PKI, ADCS, identity, and the current events that affect them. Explained clearly, without exaggeration, for the people who have to act on the information.

Practitioner-written

Every article is written by someone who has deployed, administered, or broken the systems being discussed — not by generalist security writers working from press releases.

No vendor agenda

InsecurePlanet is not affiliated with any security vendor, tooling company, or managed security provider. Recommendations are based on what works in production environments.

Depth over volume

We cover a focused set of topics with the depth they deserve. We do not publish generic security content to fill a content calendar.

Actionable by default

Every article includes specific, prioritized actions. Understanding a threat is only useful if it leads to a decision. We write for people who need to act, not just read.

Coverage

About Richard Sepulveda

Richard Sepulveda created InsecurePlanet.com to provide practical cybersecurity insight for people responsible for operating, securing, and defending real enterprise systems. The site focuses on security current events, exploited vulnerabilities, PKI, digital certificates, Microsoft ADCS, identity security, Zero Trust, and enterprise infrastructure risk.

The original InsecurePlanet documented the broad landscape of global security threats — the ways that technological dependence creates systemic vulnerability across critical infrastructure, from power grids and water systems to transportation networks and medical devices. That foundational perspective — that security is a systems problem, not just a technical one — still informs how InsecurePlanet approaches coverage today.

The modern InsecurePlanet focuses that lens on the enterprise security domain where the most consequential failures are currently happening: Active Directory, PKI, certificate services, and identity infrastructure. The goal has not changed since the site was founded — give security practitioners the information they need to make better decisions about the systems they are responsible for protecting.
