    I have been working at Tenable full-time (Less than a year)


    This is an environment of recognition for great work. Work hard and do well. It's that simple. Ideas are listened to. Teams genuinely mix together rather than having closed doors or divisions. All the global offices make massive efforts to mix and get to know each other. Training is regular. Investment in employees is in place and valuable. Really I could go on for days how much this company has impacted and changed my life.


    It's getting bigger and fast. It's hard to keep up to date with all the new faces but in saying that, it's not impossible. Really there isn't much I could complain about. We are in comfortable offices with great equipment and loads of benefits.

    Advice to Management

    Keep up the good work. Recognise and listen to your employees. When you stop doing that it's start to unfold but right now you are all over it.

    Average Interview


    I applied online. The process took 2 weeks. I interviewed at Tenable (New York, NY) in March 2017.


    I was VERY HAPPY with the service that I was given by the company, especially with Bethany Perlman, who was very helpful and accomodating through each stage of the interview process. The interview process moved quickly as well. After I applied, I got an email within two days to schedule a phone interview with her. After that, I had a online coding test through hackerrank to complete. Within two days of that I received an invite to a google hangout interview with two members of the team. That happened the following Tuesday and it seemed to go well and was a really awesome experience. I received a rejection email two days after the google hangout interview but was extremely happy with the recruitment process at tenable and really learned a lot!
