Frequently asked questions
Penetration testing costs typically range from $4,000 to over $100,000, with the majority of businesses falling between $10,000 and $30,000. Pricing primarily depends on the business size, IT infrastructure complexity, and compliance requirements. Owing to Long Island’s competitive market and the saturation of highly regulated financial and legal firms, enterprise engagements are often on the higher end of national pricing.
Look out for vendors with CREST or OSCP certifications, and, if you require PCI-DSS compliance, for those that are PCI ASVs (Approved Scanning Vendors). Additionally, opt for vendors that have experience with Long Island-specific regulations. Compare the engagement model (manual, automated, or hybrid), reporting quality, compliance alignment, and cost.
A single data breach averages $10.22 million in the U.S. On the other hand, penetration testing, as a preventive measure, costs a fraction of that and makes it a high-ROI investment. Long Island has a multitude of finance, insurance, and healthcare organizations, making it a dense regulatory environment. Hence, proactive penetration testing is essential to avoid fines and reputational damage.
Under various compliance guides, entities must conduct annual penetration testing and bi-annual vulnerability assessments, with continuous scanning or autonomous pentesting. Beyond compliance, penetration testing is advised after major infrastructure changes, new application launches, or even significant cloud migrations.
