== History ==<br />
In May 2017 ''[[TechCrunch]]'' described Convexum as having "developed a platform that takes over a malicious drone to allow it be landed safely", for sports venues, critical infrastructure and private companies.<ref name="TCConvexum2017"/> The company has said that its team "embarked on a mission in 2017". On 4 April 2023 it announced from Tel Aviv that, "under the direction of the US fund manager, Treo Asset Management" ([[Treo Asset Management]]), Convexum had been renamed Sentrycs; its chief executive was then [[Yoav Zaltzman]].<ref name="SentrycsRebrand">Sentrycs, [https://www.prnewswire.com/news-releases/sentrycs-rebrand-doubles-down-on-secure-drone-economy-with-technology-leading-integrated-counter-uas-solution-301789372.html Sentrycs Rebrand Doubles Down on Secure Drone Economy with Technology-Leading Integrated Counter-UAS Solution] ''PR Newswire'', 4 April 2023, accessed 10 November 2026.</ref><br />
<br />
=== Acquisition by Ondas ===<br />
On 4 November 2025 [[Ondas Holdings]], a Nasdaq-listed maker of autonomous drones and robots, agreed to buy Sentry CS Ltd, which it called "an Israel-based global leader" in counter-drone technology "across both defense and civilian environments". Ondas said that Sentrycs' systems protect "airports, borders, bases, and sensitive facilities", and that it would combine them with its own Iron Drone Raider interceptor.<ref name="OndasSentrycsAgree"/> It completed the deal on 18 November 2025, saying that Sentrycs had about 200 deployments in more than 25 countries and would extend its reach to "Tier-1 defense, public safety, and security agencies".<ref name="OndasSentrycsComplete"/><br />
<br />
== Founders and military service ==<br />
* [[Gilad Sahar]], co-founder and chief executive of Convexum: ''TechCrunch'' wrote in 2017 that he had more than ten years' experience leading research on "protocols reverse engineering, dating back to his service in the IDF elite intelligence unit 8200 during which he won several accolades" ([[Unit 8200]]; [[Aman|Intelligence Corps]]), and that "Following his army service, Gilad was part of the pioneering team of Cellebrite's mobile forensic division", where he managed decoding research for four years.<ref name="TCConvexum2017"/><br />
