20+ years Hands-on experience in Cyber Security, Networking, SaaS, Research, Machine…

Oren Nechushtan is an Israeli technologist and entrepreneur who represented Israel at the 1993 International Mathematical Olympiad, winning a silver medal. He holds a B.Sc. in Mathematics from the Technion and an M.Sc. in Computer Science/Mathematics from Tel Aviv University, where he did computational-geometry research (exact Minkowski sums) and contributed to the CGAL arrangement package; his paper 'On the space chromatic number' (2002) remains well cited. He then spent roughly 15 years at Forescout Technologies, rising to Senior Director of Research, co-authoring security research and patents. In 2023 he co-founded Menthoda, where he serves as CTO and board member.

Notes

Career arc spans three phases: academic computational geometry (TAU/CGAL) to ~2005, then 15+ years at Forescout (engineer → Sr. Director of Research), then founding Menthoda in 2023 — moving from researcher to security-company operator.Jul 2023
Represented Israel at the 34th IMO in Istanbul 1993, winning a Silver Medal with 49 points (rank 49), one of Israel's medalists that year.Jul 1993
Listed as CTO & Co-Founder of Menthoda Ltd. in IVC's company card, alongside CEO & Co-Founder Oshrat Aharon — the leadership pair behind the firm.Jan 2024
First-named author of 'On the space chromatic number' (Discrete Mathematics, 2002), a well-cited result on coloring Euclidean space; the paper is still cited 100+ times, making it his most durable academic contribution.Jan 2002
IMO team scores: 6,3,3,7,6 on problems 1-5 (total 49, 88.35%) behind teammate Omer Angel's gold — early evidence of elite mathematical ability that later shows up in his computational-geometry research.Jul 1993
Named inventor on multiple Forescout Technologies patents (e.g. 'Name translation monitoring' US 12348546, with Oded Comay; and intrusion-detection/dynamic-security patents), positioning him as a long-term Forescout IP contributor.Jul 2024
Co-authored Forescout research on 'exotic' DICOM malware that blurs the line between medical imaging and diagnosis (2019), reflecting his cybersecurity research leadership at the company.May 2019
Described by TAU's Computational Geometry Lab as working on 'Exact Minkowski Sums of Polygons With Holes' — his M.Sc. research lineage under Dan Halperin/Micha Sharir.Jan 2005
His space-coloring result was highlighted as the best known lower bound in Soifer's 'The Mathematical Coloring Book' — a standard reference citing his work by name.Jan 2009
Contributed to CGAL's arrangement package ('The Design and Implementation of Planar Arrangements of Curves in CGAL'), alongside Sigal Raab and Tali Zvi — early open-source geometry work before cybersecurity.Jan 2007
Israeli winners registry lists him under his Hebrew name אורן נחושתן with one Olympic achievement (1993 silver).Jan 2020
