Public Sector Threat Advisory Service

Proactive Zero-Day Research & Coordinated Disclosure for Government CERTs

Cyber Espial empowers national CERTs and public sector cybersecurity organizations with advanced zero-day vulnerability research and sovereign threat mitigation.

We identify unknown security flaws in critical national infrastructure, e-government platforms, and sovereign cloud environments before malicious state-sponsored actors can exploit them—delivering secure PGP reports and joint patch validation.

Core stages of our government advisory engagement:

Authorized scope definition, legal compliance, and strict NDA/RoE protocols

Non-disruptive zero-day discovery across e-governance portals and supply chains

Encrypted PGP advisory handover with comprehensive CVSS v3/v4 impact metrics

Patch validation, emergency mitigation guidance, and national threat intelligence

End-to-End Government Threat Research Lifecycle

Scope & Compliance

Phase 1: Authorization

Establishing legal frameworks and strict Rules of Engagement (RoE) across sovereign digital assets, e-governance platforms, and critical information infrastructure (CII).

Sovereign NDAs: Ensures strict non-disclosure compliance and total confidentiality matching national security protocols.

Zero-Day Research

Phase 2: Discovery

Non-disruptive, advanced security audits targeting government portals, API gateways, supply chain software, and legacy public sector systems to locate unknown zero-days.

Zero-Impact Testing: Protects operational uptime and availability without employing destructive methods.

CERT/CSIRT Handover

Phase 3: Disclosure

Secure, encrypted advisory submission to national response teams including step-by-step Proof-of-Concept (PoC), CVSS v3/v4 metrics, and technical impact analysis.

Joint Evaluation: Direct collaboration with CERT security engineers to triage risk priority and urgency.

Patch Validation

Phase 4: Remediation

Assisting government IT personnel with emergency mitigation advice, WAF firewall rule updates, temporary hotfixes, and rigorous post-patch re-testing.

Zero-Bypass Check: Verifies that implemented fixes completely neutralize the risk without residual flaws.

Threat Intelligence

Phase 5: National Alerts

Co-authoring nationwide advisories, system-hardening guidelines, and strategic prevention protocols to protect broader public and private sector infrastructure.

Ecosystem Defense: Translates zero-day findings into actionable security baselines for all state ministries.

Authorized Scope & Strict Legal Compliance

We initiate engagements by finalizing a robust legal framework with government entities to establish clearly defined boundaries for sovereign digital asset research. Through comprehensive Rules of Engagement (RoE), we map out the authorized scope covering target government ministries, citizen portals, critical information infrastructure (CII), and public utility networks.

To guarantee absolute confidentiality and legal protection for zero-day disclosures, we strictly enforce Non-Disclosure Agreements (NDA) & Compliance standards aligned with national security protocols and data sovereignty regulations.

Offensive Research & Advanced Zero-Day Discovery Methodologies

E-Governance Portals

Deep technical evaluations of citizen portals, authentication endpoints, and public-facing ministry web applications to identify hidden logic flaws before external adversaries exploit them.

Database & API Gateways

Rigorous auditing of sovereign cloud databases and REST/GraphQL API gateways used across government networks to prevent unauthorized data exposure and broken object-level authorization.

Supply Chain Security

Evaluating critical third-party software vendors, sub-contracted digital components, and open-source dependencies integrated into public sector infrastructure for embedded vulnerabilities.

Zero-Impact Methodology

Ensuring 100% continuous uptime and public availability during all testing phases by strictly prohibiting destructive techniques, denial-of-service tests, or accidental data corruption.

Legacy Infrastructure Audits

Uncovering architectural vulnerabilities in older municipal systems, unpatched government servers, and legacy databases that lack modern security monitoring controls.

Zero-Day Vulnerability Research

Advanced source code review and protocol analysis to discover previously unknown (zero-day) software vulnerabilities before cyberespionage groups or state-sponsored APTs can weaponize them.

Coordinated CERT / CSIRT Vulnerability Reporting Framework

Whenever a critical or zero-day vulnerability is identified, it is securely transferred directly to national response teams using standard ISO-compliant disclosure protocols.

Encrypted Advisory Handover: Full vulnerability advisories are delivered to national CERT/CSIRT teams through PGP-encrypted and dedicated secure communication channels.

Proof-of-Concept (PoC) & Impact Matrix: Technical reports include step-by-step reproduction steps, verified PoC scripts, and precise system-level risk assessments.

Standardized CVSS Scoring: Vulnerabilities are evaluated against globally accepted CVSS v3.1 / v4.0 metrics to assign exact and standardized severity scores.

Triage & Joint Evaluation: Direct coordination meetings are held with CERT security engineers to establish remediation priorities, impact urgency, and patch timelines.

Secure Chain of Custody: Advisory details and threat telemetry data are handled within strictly controlled environments in compliance with sovereign national security mandates.

Emergency Mitigation Support & Rigorous Patch Verification

Following formal vulnerability reporting to CERT, we collaborate closely with government IT departments to initiate the critical phase of patch implementation and security verification.

Emergency Mitigation Guidance

Providing government IT departments and system administrators with immediate temporary hotfixes, emergency configuration adjustments, and WAF firewall rules to cover active exposures.

Re-Testing & Patch Verification

Subjecting systems to rigorous follow-up testing once vendor patches or code fixes are applied to verify that the identified vulnerabilities have been completely and securely resolved.

Zero-Bypass Architecture Review

Ensuring that no bypass paths or residual security flaws remain after patching, preventing external threat actors from regaining unauthorized access to sovereign systems.

Phase 5: Intelligence & Prevention

National Alerts, Guidelines & Threat Intelligence

Once vulnerabilities are fully remediated, wide-scale advisories are released to elevate national cybersecurity standards. Cyber Espial collaborates directly with national CERT/CSIRT organizations to co-author National Security Advisories, equipping both public and private sector entities with proactive threat insights.

We issue hardening checklists, secure architecture guidelines, and proactive defense protocols tailored for government ministries and associated departments. Additionally, following official government authorization, we publish redacted or anonymized Coordinated Public Disclosure case studies to strengthen the resilience of the broader ecosystem.

Trusted Expertise in Sovereign Threat Advisory & Zero-Day Research

Strict Legal & Data Sovereignty: Standard commercial vulnerability scanners often breach jurisdictional laws. Our engagements strictly comply with national data sovereignty regulations, NDA protocols, and authorized Rules of Engagement (RoE).

Non-Disruptive Zero-Impact Methodology: Public sector portals and critical infrastructure require 100% uptime. We conduct advanced offensive research without deploying destructive techniques or risking citizen data availability.

Coordinated CERT Collaboration: Rather than exposing flaws publicly, we provide PGP-encrypted advisory handovers, precise CVSS metrics, and direct patch validation support to national response teams.
