Our Mission
CyberSure was established to resolve the single most critical vulnerability in corporate risk management: the structural disconnect between IT security controls, evolving regulatory mandates, and cyber insurance policies.
Every year, executive teams and boards approve substantial cyber insurance premiums under the assumption that the enterprise is fully protected. In reality, when a ransomware attack or major breach strikes, insurers frequently dispute claims or rescind coverage retroactively, citing Material Misrepresentation. This occurs because underwriting forms are completed without rigorous, legally backed verification of the underlying IT environment.
CyberSure bridges this divide. We conduct independent, legally privileged readiness audits to ensure that when a crisis hits, your policy performs as intended and claims are honored in full.
The Four Pillars of Our Practice
While traditional market offerings force organizations to choose between technical consultants who cannot interpret insurance exclusions, or brokers and legal counsel who lack technical depth, Adv. Onn fluently speaks the three essential languages of cyber resilience: Commercial Insurance Law, Global Underwriting, and Technical IT Architecture.
20+ Years in Insurance Litigation & D&O Governance
Decades of experience analyzing complex policies, restrictive endorsements, warranties, and coverage exclusions.
Comprehensive protection for corporate boards and officers against personal liability, derivative suits, and regulatory exposure.
Global Cyber Underwriting Expertise – CCIS (London)
Certified Cyber Insurance Specialist (CCIS), credentialed through the specialized London insurance and cyber market.
Native command of European and Lloyd’s syndicate underwriting frameworks, translating technical controls into language that satisfies global underwriters.
Certified Information Security & Privacy Leadership – CISO & DPO
Hands-on command of enterprise security architecture: validating immutable backups, enterprise MFA enforcement, and EDR/SOC efficacy.
Authoritative navigation of strict privacy and resilience regimes, including Israel’s Privacy Protection Law Amendment 13, the EU’s DORA, NIS2, and GDPR.
Attorney-Client Privilege by Design
Unlike standard IT or GRC consultancies whose assessment reports are discoverable in court, all CyberSure reviews are conducted directly under formal legal privilege.
Identified vulnerabilities remain strictly confidential and cannot be subpoenaed or weaponized by insurers as evidence to deny a claim.
