Review Slideshow
★★★★★

“Our first pentest with Vanguard found real gaps.” – Sarah B., D.T. Group

Our first penetration test with QuantumSabre’s VANGUARD service was eye-opening. Unlike previous scans, VANGUARD’s comprehensive approach—combining manual testing and advanced threat simulations—uncovered critical vulnerabilities we hadn’t noticed before, like weaknesses in network segmentation and unpatched systems. The report was clear, actionable, and prioritized, helping us address the most urgent risks first.

The best part is the monthly subscription. It makes our budget easier to manage, and for a fraction of the cost, we get continuous defense and yearly pentests. VANGUARD’s service has significantly strengthened our security, and we highly recommend it for businesses seeking ongoing, high-assurance protection.

★★★★★

“Vanguard’s continuous defense gives us peace of mind.” – Mark T., GlobalTech

After a thorough review of our security needs, we decided to try QuantumSabre’s VANGUARD service. The monthly subscription is a game-changer — it fits well within our budget, and the continuous defense means we’re not just reactive but proactive in tackling cyber threats. VANGUARD’s penetration testing uncovered vulnerabilities in our network we didn’t know existed, including a potential exploit in our outdated firewall configurations.

The detailed reports provided clear, actionable steps to fix those vulnerabilities, and knowing that we’ll get another penetration test next year gives us the assurance of sustained protection. For what we’re paying, the value is exceptional. We highly recommend VANGUARD to any business that takes cybersecurity seriously.

🛡️ VANGUARD: Beyond Cybersecurity—A Cyber Warfare Strategy

✅ AI-Powered Threat Intelligence & Predictive Defense
Unlike GUARDIAN, which focuses on real-time monitoring, VANGUARD anticipates and neutralizes cyber threats before they escalate using AI-driven adversary tracking.

✅ Red Teaming & Active Cyber Threat Suppression
VANGUARD doesn’t just defend—it launches controlled attacks against your systems to expose weaknesses and fortify them before real hackers do.

✅ Zero-Trust Security Architecture & Advanced Deception Techniques
With nation-state-grade deception tactics, network segmentation, and adaptive access control, VANGUARD makes your organization invisible to cybercriminals.

✅ Dark Web Counterintelligence & Insider Threat Prevention
While GUARDIAN monitors the dark web, VANGUARD actively disrupts stolen credential use, tracks cybercriminal activity, and prevents insider sabotage.

✅ 1-Hour Incident Response SLA
GUARDIAN offers 4-hour emergency response, but VANGUARD guarantees response and mitigation within 1 hour, significantly reducing attack impact.

✅ Executive Security Consulting & Compliance Leadership
VANGUARD provides high-level security briefings, compliance risk assessments, and attack simulations for executive teams.

⚠️ The True Cost of a Targeted Cyberattack

For businesses in finance, critical infrastructure, defense, healthcare, and high-risk industries, a cyberattack is not just a financial setback—it can cripple operations, expose classified data, and destroy reputations.

💰 Ransomware Attacks

High-value targets often face ransom demands of £500,000+, plus millions in downtime losses.

⏳ Operational Downtime

A single breach can halt operations for weeks, leading to supply chain disruptions, regulatory fines, and loss of contracts.

📉 Reputation & Compliance Risks

A data breach can trigger lawsuits, regulatory audits, and loss of investor confidence—damaging a business beyond financial losses.

⚖️ Regulatory Fines & Legal Exposure

Businesses handling sensitive data face UK GDPR fines, supply chain penalties, and legal liabilities exceeding millions

🚨 State-Sponsored & Targeted Attacks

Cybercriminal organizations, nation-state actors, and hacktivists specifically target high-value businesses—making basic cybersecurity inadequate.
