We've just completed a rather painful evaluation of both Entro and Linx, driven by a CISO mandate to "solve PAM" after a particularly embarrassing audit finding. I'm here to tell you that the marketing hype from both vendors is, as usual, several orders of magnitude greater than the actual utility of the products. Having spent the last three months neck-deep in demos, PoCs, and internal political wrangling, I can offer a ground-level view that cuts through the sales decks.
Let's start with the core philosophy. **Entro** approaches the problem like a typical security startup: it wants to be a platform. It's obsessed with discovery, mapping, and "secret sprawl" visualization. **Linx** (formerly Linx Security) comes from a more operational, DevOps-toolchain angle, focusing on the mechanics of just-in-time access and session management. This fundamental difference dictates everything that follows.
Our key findings, which ultimately led us to pick neither for a full rollout:
**Entro Security**
* **The Good:** Their discovery and inventory engine is genuinely impressive. It connected to our AWS Org, GCP folders, GitHub, GitLab, HashiCorp Vault, and even our messy collection of legacy on-prem SSH bastions. The graph it generated showing which human and machine identities could access what was a sobering sight, worth the price of admission for the security team's awareness alone.
* **The Bad:** It's a monitoring and reporting tool first, an access tool second. The actual mechanism for JIT elevation or break-glass is often a clunky web-based proxy or requires deep integration work. Their pricing model is based on "secrets discovered," which feels like a perverse incentive—the messier you are, the more you pay, forever.
* **The Ugly:** The platform wants to own everything. To get real value, you're funneling all access requests through their portal. This creates a single point of failure and a massive change management hurdle for engineers who live in terminals and IDEs. Their response to this concern was essentially "they'll get used to it."
**Linx Security**
* **The Good:** The engineering experience is vastly superior. Their approach of integrating with existing tooling (Slack, CLI, IDE plugins) for access requests and then managing the actual session through ephemeral credentials or short-lived bastions is far less disruptive. It feels like a tool, not a prison.
* **Bad:** The discovery side is an afterthought. It relies heavily on you already knowing what you have and where it is. In our evaluation, it missed entire swaths of service accounts and legacy systems that Entro found instantly. You're buying a precise screwdriver, but you still need your own magnetic tray to hold all the screws.
* **The Ugly:** The product feels less cohesive. You're stitching together the request workflow, the credential management, and the session recording from different modules. Their support was responsive but often gave us "workaround" solutions that felt like beta features.
**The Verdict & The Rebellion**
We're not buying either. The business wanted a silver bullet, but we're architects, not magicians. We're implementing a layered, boring, and cheap approach:
1. **Discovery & Inventory:** We're using **OpenCTI** (for the graph) and some home-grown scripts using AWS IAM Access Analyzer and GCP Policy Intelligence. Cost: engineer time.
2. **JIT for Cloud:** Using **AWS IAM Roles Anywhere** and **GCP's context-aware access** paired with our existing identity provider (Okta). For elevated access, we're using temporary role assumption with mandatory MFA and logging all calls to CloudTrail. No third-party proxy needed.
3. **Secrets Management:** Doubling down on **HashiCorp Vault** with dynamic secrets for databases and services.
4. **Break-Glass:** A hardened, isolated **AWS SSM Session Manager** configuration with approval workflows in Jira Service Management (which we already have). It's ugly but auditable.
The total cost is a fraction of either vendor's annual quote, and it uses services we already own and understand. The downside? It requires actual engineering and operational discipline, which is what everyone was trying to avoid in the first place. My advice: unless you're in a heavily regulated industry that demands a vendor checkbox, you can probably build 80% of the functionality for 20% of the cost and complexity. Just be prepared for the internal fight when you tell leadership you're not buying the shiny thing.
