Pre-IPO Security Assessment
Cybersecurity readiness evaluation for companies preparing for public listing — clean disclosure, investor confidence, and valuation protection throughout the IPO process.
Overview
Public listing is one of the most consequential inflection points in a company's lifecycle — and cybersecurity is now a material factor in its success. Institutional investors, underwriters, and regulators scrutinise security posture with unprecedented intensity. An undisclosed vulnerability, unreported breach, or inadequate governance framework can delay timelines by months, reduce valuations, or create post-listing litigation exposure before the first quarterly earnings call.
SEC cybersecurity disclosure rules require material cyber risk and incident reporting in registration statements. The EU Prospectus Regulation demands risk factor disclosure, and NIS2 compliance applies to many companies entering European public markets. Underwriters increasingly engage specialist assessors to evaluate disclosure accuracy — findings that contradict prospectus representations create immediate liability for issuers and directors.
Intarmour's Pre-IPO Security Assessment provides Private Equity-backed companies with a rigorous, independent evaluation of cybersecurity readiness. Our methodology examines technical infrastructure, governance frameworks, regulatory compliance, data protection practices, and incident response capabilities — producing a readiness report that identifies material risks, quantifies remediation requirements, and provides the evidence base for accurate prospectus disclosure. We operate within pre-listing confidentiality constraints with strict information barriers throughout.
Companies that demonstrate mature cybersecurity governance command stronger investor confidence during roadshows. Those that discover material deficiencies during the listing process face the choice between disclosure that dampens appetite and non-disclosure that creates regulatory exposure. Our assessment ensures sponsors and management teams confront these questions on their own timeline, with adequate runway for remediation.
Assessment Scope
Governance & Risk Management
Evaluation of board-level cybersecurity oversight, risk management frameworks, CISO function maturity, and policy documentation. Assessment of whether governance satisfies institutional investor expectations and regulatory disclosure standards for public entities.
Technical Infrastructure Review
Examination of network architecture, cloud infrastructure, application security, vulnerability management, and legacy system exposure. Identification of technical debt representing material risk for disclosure or remediation prior to listing.
Data Protection & Privacy
Assessment of data classification, cross-border transfer mechanisms, consent management, and privacy programme maturity against GDPR, sector-specific regulations, and jurisdictional requirements relevant to the operational footprint.
Third-Party Dependencies
Risk assessment of critical vendor relationships, supply chain dependencies, and outsourced technology services. Evaluation of contractual security provisions, SLA adequacy, and concentration risk requiring prospectus disclosure.
Incident Response Capabilities
Assessment of detection, classification, containment, and recovery capabilities. Review of historical incident records, breach notification procedures, and crisis communication readiness against public company reporting obligations.
Regulatory Compliance Status
Mapping of applicable regulations across all operating jurisdictions. Gap analysis against NIS2, DORA, sector-specific frameworks, and securities regulation disclosure requirements. Quantified remediation cost estimates for identified gaps.
Deliverables
IPO Readiness Report
Assessment document detailing cybersecurity posture across all evaluation dimensions.

Formatted for Investment Committee members, legal counsel, and underwriter teams. Includes a clear go/no-go recommendation on listing readiness with specific conditions to satisfy.
Remediation Roadmap
Prioritised action plan organised by criticality and IPO timeline dependencies. Each item includes effort estimates, cost projections, and explicit linkage to disclosure impact. Distinguishes between items to resolve before listing and those addressable post-IPO with appropriate disclosure. Aligned with prospectus drafting schedules and target listing dates.
Investor Presentation Brief
Executive summary for institutional investors presenting cybersecurity posture in terms that resonate with investment decision-makers.

European FinTech IPO Preparation
Context
Mid-cap financial technology company preparing for Euronext listing, backed by a European growth equity fund. Processed payment transactions across six EU member states, holding sensitive financial data for several hundred thousand business customers. The sponsor required independent cybersecurity assessment to validate prospectus disclosure and identify material risks. Listing targeted within six months.
Findings
Three categories of material concern: legacy API infrastructure with authentication vulnerabilities representing a data exposure pathway affecting a significant portion of customers; cross-border data handling practices failing GDPR transfer requirements for two jurisdictions; and an incident response framework lacking public-company maturity, with no breach notification procedures aligned to securities disclosure timelines.
Remediation
14-week programme addressing all deficiencies. API security overhaul with authentication hardening, rate limiting, and legacy endpoint deprecation. Data handling restructured with compliant transfer mechanisms. Incident response elevated to public-company standard with tabletop exercises and securities counsel integration. CISO reporting line to the board established with quarterly cybersecurity committee reviews.
Outcome
Successful Euronext listing on the original timeline with clean cybersecurity disclosure. Underwriter due diligence confirmed remediation completeness. Institutional investors cited cybersecurity governance as a differentiator relative to comparable listings. The sponsor subsequently engaged Intarmour for two additional portfolio company pre-listing assessments.
Ideal Client Profile
Serves PE-backed companies in active preparation for public listing on European or international exchanges, and sponsor firms requiring independent cybersecurity validation. Particularly relevant for technology, financial services, healthcare, and data-intensive sectors where security posture directly influences investor confidence and regulatory scrutiny.
Common engagement drivers: sponsor firms initiating IPO preparation for companies with material technology infrastructure; management teams pre-empting underwriter findings; board directors requiring independent assurance on disclosure accuracy; companies with historical incidents requiring documented remediation evidence; or growth-stage companies whose security governance has not kept pace with operational scale.
Engagement Model
Delivered as a fixed-scope engagement over four to eight weeks, calibrated to infrastructure complexity and listing timeline. Commences with a scoping workshop to define evaluation boundaries, prioritise assessment dimensions by sector-specific risk, and align deliverables with sponsor and underwriter requirements.
Fixed fee agreed at commencement with no variable components, providing budget certainty across multiple advisory workstreams. Remediation support, where required, is scoped and priced as a separate engagement.
All activities conducted under non-disclosure agreements with pre-listing confidentiality provisions. Assessment data stored on EU-sovereign infrastructure with automatic deletion upon conclusion. Intarmour maintains strict independence — our findings serve accurate disclosure and informed decision-making, not any particular listing outcome.
