    TachTech has been named to the #Inc5000 for the ninth time - a distinction achieved by fewer than 1% of companies that have ever applied. This recognition reflects how we’ve grown: strong relationships, a people-first culture, and trust earned by consistently delivering for our clients and partners. “Nine years on the Inc. 5000 is a great milestone, but what matters most is where we go from here. We’ve built a strong foundation, and I believe TachTech’s biggest growth is still ahead of us,” says Larry Letow, TachTech’s CEO. Thank you to our TachTech team, clients, and partners for being part of our continued success. #tachtech #AI #cybersecurity #engineeringservices

  • Building Momentum at #BlackHat2026 #BlackHat2026 was TachTech's most impactful yet. A growing team, real momentum, and a week of the right people in the right rooms. We kicked off Black Hat co-hosting the #NextGen CISO Forum, bringing together emerging security leaders for candid conversations about the parts of the CISO role that don’t appear in a job description. From there, the focus turned to what’s next for TachTech. Partner meetings throughout Tuesday and Wednesday gave us the opportunity to strengthen relationships, discuss where we’re headed, and explore how we can continue building together. As TachTech continues to grow across the country, Black Hat gave us an important opportunity to strengthen existing relationships, build new ones, and have meaningful conversations about where we’re headed.

    #BlackHat week is almost here. TachTech is looking forward to hosting a private evening Tuesday night at The #PinkyRing by Bruno Mars at the Bellagio. A space for quality time with our close friends and partners, amid the briefings and meetings of Black Hat week. Live music always helps the soul step away from the long days. Good music, good conversation, and a little breathing room. Thank you to Harmonic Security and Reach Security for your support! See you in Vegas!

  • On August 3rd in Las Vegas, TachTech CEO Larry Letow moderates "Inside the Boardroom" at the #NextGenCISO Forum bringing together executives with decades of experience navigating cybersecurity from both sides of the table. Drawing on his own experience as a CEO, board member, and cybersecurity executive, Larry will lead a conversation focused on what #CISOs need to know about communicating risk, how to speak the language of business risk and what it takes to move from trusted technologist to trusted executive. For aspiring CISOs attending this event, this is a rare chance to understand how the strongest security leaders earn a seat at the table. See you at #BlackHat

  • This 4th of July marks #250 years since independence was first declared, and defending it has never stopped. It used to mean standing a post. Today it also means securing the systems and data that hold up daily life. Grateful to everyone doing that work, in whatever form it takes. Happy Independence Day from TachTech!

  • The hardest part of becoming a #CISO isn't the technology. It's the moment you walk into a boardroom for the first time and realize the game has completely changed. No rulebook. No warm-up. Just executive presence, board dynamics, internal politics, and personal liability, all at once, all accelerated. It's a brutal learning curve. And for too long, it's been a lonely one. That changes August 3rd in Las Vegas. TachTech is proudly partnering with Whiterabbit, HITCH PARTNERS, Code Red Partners and Scale Venture Partners to bring the #NextGen CISO Forum to Vegas, during #BlackHat2026 NextGen CISO Forum | August 3, 2026 | 12:00–5:30 PM | By Nomination Only Built for the security leaders who are ready for what's next. This is a rare opportunity to hear directly from some of the most respected names in security. A chance to build a genuine peer-to-peer network with others in the exact same moment of their career. #CISO's if you have someone in your organization who's on the CISO track, this is the room you want them in. Nominate a rising leader: luma.com/v2ahq6c5 Questions? DM Kim Paradise on the #TachTech team.
