Pros

Joined after couple years doing SDR in regular saas and switching to cybersec here was great move. Conversations are way more interesting clients have real problems and you actualy feel like you helping them not just hitting quota Team is super strong. Anyone you ping on chat will help no ego no gatekeeping. Lot of senior AEs and SEs who been in cybersec for years and they share openly. Onboarding was smooth had clear ramp up plan from week one

Cons

Quarter ends can be stressful with multiple campaigns running in paralel. Internal docs not always up to date so sometimes faster to just ask someone then search wiki

Pros

Came here from pure technical role and presales turned out to be perfect mix of tech and client work. You get to design real solutions for real problems, not just push slides. Clients are mostly mid market and enterprise so conversations are serious and technical, no time wasted on small talk Team is what makes this place special. Everyone is willing to help, you can ping anyone from SOC analyst to head of pentest and get answer fast. Knowledge sharing happens organicaly, not forced. Also good mix of seniors and juniors so you learn and teach at same time Flexibility is real. Remote works fine, hours are reasonable, nobody counts minutes. As long as deals move and clients are happy you have full trust from managment

Cons

Sometimes you get pulled into too many parallel opportunities and have to prioritize hard. Tooling for presales workflow could be improved, we use mix of different platforms and not everything talks to each other smoothly

Pros

Honestly one of the best places I worked at for growing as a cybersecurity professional. The bar is really high here and you feel it from day one. People around you are smart and motivated, and that pushes you to be better every week Yes the work is hard. But cybersecurity is hard, that is just how it is. You deal with real threats, real customers, problems that do not have a clean answer in any textbook. If you want easy and predictable this is probably not the place for you. If you want to actually grow and become strong in this field, this is exactly where you should be Team is great. People share knowledge, help each other, and you can ask any question without feeling stupid. Management trusts you to own your work and gives you space to try things. They support you when things get tough there are tons of opportunities if you want to take them. New projects, new technologies, new directions all the time. People who show initiative actually get noticed and get real chances to step up. The culture is also very human, flexible hours, remote options, respect for your personal life. Feels like a team not a corporate machine Lots of challenges every day, but in a good way. You finish the month and realize you grew. That feeling is hard to find in other places

Cons

Pace is intense and the workload can be heavy during busy weeks. Priorities sometimes change fast because the field itself changes fast. Not every process is fully polished yet but you can see the company is working on it. If you need a calm 9 to 5 this might not be the best fit for you
