Pros: Great management. Great environment. Great work.

Cons: No downsides to speak of.

Pros: The only reason anyone stays at this company is because they get to work from home, or because it doesn't require any security clearance. Everyone on my team was actively seeking new employment or simply riding it out until the company sinks. My own boss at one point told me that the only reason anyone was there was because of the health insurance, or some stubborn sense of loyalty. That is a pretty miserable state of affairs. Sincerely, the only pro is that eventually you won't have to work there anymore.

Cons: If you are an engineer, your skills will atrophy while you are here. I am a frontend developer. I work with JavaScript. Eighty percent of my two-plus years at this company was spent writing automation tests in Python. That is not an exaggeration. The week before I left this gong show, I discovered that literally zero of these tests had actually been running in our build plans. Hours and hours and hours of several engineers' time was completely wasted, while a few good ol' boy managers covered each other's rear ends on what was really going on. I had a family member in critical condition at a hospital several hours' drive away. I had spent one afternoon planning with my family who would watch the kids, who would take care of the pets, and who would go visit at what times. I missed approximately four hours of work for this. The next day, when informed my boss, she replied, "Is the automation done yet?" This was probably the most disgusting thing anyone has ever said to me in a workplace. I immediately knew it was time to find a new job, and I didn't really care to hide my anger. This led to me being put on a PIP, and about three days later, I got an email with no message in it, simply a termination notice form attached. Keep it classy over there, Tenable. Your reputation is growing.

Pros: Really friendly to telecommuters. I have worked remotely for a lot of shops over the last ~10 years, and Tenable does this right. No nonsense, no preferential treatment. My manager at least was one of the most laid-back people I've met, professionally or otherwise. Despite disagreeing on a lot of things, coworkers were easy to get along with. If you're looking for easy work and are a halfway competent programmer, you'll find it here. I, however, want to be challenged (see below). For a less experienced developer looking for a place to grow in the beginning of their career, Tenable would be an okay choice to learn the basics. It's an extremely forgiving environment where (at least on the team I was on) mistakes won't cause business-disrupting catastrophes. This is great for newer developers, but I needed much more culpability in my work (again, see below).

Cons: I wasn't challenged, at all. Most of the job was maintaining existing code, and there weren't any hard problems, just "fix this," "incrementally improve that," or "copypaste this and slightly modify it to suit this new thing." It was tedious, unrewarding busy-work that doesn't make me excited to get up in the morning. There were no real challenges in sight, just keeping up with the endless tide of small changes and fixes. I couldn't see myself doing that forever; it was a shameful waste of my abilities. There were no real risks, either. Nothing I did had any risk to it; either the code didn't work and harmlessly failed, or it did what it needed to do, and the world marched quietly, uneventfully, on. Sure, I was helping make the internet incrementally more secure, but not in any real, measurable, lasting sense. It was like I was adding bricks on top of an already-built dam. I was improving the situation, but drastically less than the people who came before and built the framework I improved every day. I identified with the mission (just not in the way the marketing department phrased it), but without a sense of being challenged, I felt like I wasn't really improving myself, like I was standing still in the most rapidly moving field on the planet. Technology-wise, it's a very corporate environment, very unfriendly to open source. This was probably the basis for everything else that put me off the company. Note that this was a con from *my* point of view, and that others may prefer it. I know my coworkers certainly did.
