Assac Networks
Tel Aviv-based maker of ShieldiT, a mobile anti-tapping and encrypted-communications app for government and defense users, now majority-owned by US-listed ASPIS Cyber Technologies.

Assac Networks, based in Tel Aviv, Israel, builds mobile and network security products aimed at protecting government agencies, defense organizations, and telecom/industrial operators from eavesdropping, tampering, and network intrusion. Its flagship product, ShieldiT, is a mobile security application that layers encrypted voice and messaging, anti-tapping protection, and device-integrity monitoring on top of standard iOS and Android handsets, targeting customers who need secure communications without issuing dedicated hardened phones. The company also sells SCADA-focused intrusion detection and prevention systems for industrial and telecom networks.
Founded in 2011 by veterans of Israel’s defense and intelligence sector, Assac built its early business around government and military communications-security contracts, including a publicized ShieldiT deployment with a South American security force. In 2022, US-listed ASPIS Cyber Technologies acquired a majority stake in the company for a reported $7.5 million, and the two brands now describe themselves as operating jointly as ASPIS/ASSAC, pairing Assac’s mobile-security engineering with ASPIS’s US market access.
Assac remains a small, specialized player. It competes less on volume and more on tailored, defense-grade mobile security for government and critical-infrastructure buyers who cannot rely on commercial MDM/UEM tools alone. Given the limited independent financial disclosure since the 2022 change of control, and the small size of parent ASPIS, buyers should verify current capabilities and support directly rather than relying solely on combined-entity marketing material.
Innovation Matrix Assessment
The core ShieldiT product has evolved incrementally for years with no major documented platform expansion since the 2022 ASPIS transaction, consistent with a very small engineering team.
Reported headcount is around 10 employees, tiny for a vendor selling to government and defense customers, though the company has sustained operations and delivered documented contracts since 2011.
Beyond the 2022 ASPIS investment, public momentum signals are thin - no independently reported new funding rounds, major customer wins, or product launches were found since then.
ShieldiT's anti-tapping and encrypted-communications layer for unmodified consumer smartphones is a real niche differentiator versus carrier-grade or hardware-based secure phones, though the underlying approach is not unique to Assac.
Government and defense deployments, including a reported South American security-force contract, have been covered by defense trade press, but no independent lab testing or certification of ShieldiT's security claims was found.
Demand for anti-tapping, anti-spyware mobile protection among government and defense buyers has grown amid high-profile mobile surveillance incidents, keeping this niche relevant even though Assac's addressable market is narrow.
Why CISOs Should Care
For CISOs at government agencies or critical-infrastructure operators who need a lightweight anti-tapping layer on standard smartphones rather than dedicated hardened devices, ShieldiT addresses a real gap - though current capabilities should be verified directly given the company's small size.
What Makes It Different
Unlike enterprise MDM/UEM vendors, Assac focuses narrowly on communications encryption and anti-tapping detection for standard consumer smartphones, aimed at defense and government users rather than broad enterprise mobility management.
The Matrix Verdict
42/100 — EMERGING / UNRANKED
Assac Networks fills a narrow but real niche in defense-grade mobile communications security, but its tiny headcount, sparse recent public disclosure, and 2022 change of control under a small US-listed parent make claims about post-acquisition momentum difficult to verify independently.
Editorial Note: Claims vs. Verified Findings
Assac's mobile and SCADA security capability claims and the $7.5 million ASPIS investment figure come from vendor and press-release sources. The South American ShieldiT government contract was independently reported by defense trade press. No independent security testing or customer-count validation was found for ShieldiT's efficacy claims.
