🔐 Stronger. Smarter. Always Secure.

The Cost of Choosing the Wrong Cybersecurity Firm

A single breach can wipe out years of progress — not just financially, but reputationally. Relying on cheap, generic security providers or underpowered tools means threats go undetected, responses are delayed, and attackers have time to move laterally, exfiltrate data, and destroy trust.

Cybersecurity isn’t where you cut corners.
It’s where you draw the line.

The financial hit? On average, £3–5 million in losses from downtime, legal action, regulatory fines, and customer churn. The reputational damage? Often irreversible — clients leave, trust evaporates, and your brand becomes a cautionary tale.

Guardian was built to prevent exactly that — real protection, real experts, real results.

🛡️ GUARDIAN: Advanced Cybersecurity That Adapts to Your Business

✅ AI-Powered Threat Intelligence & Automated Response
Unlike SENTINEL, which focuses on alerting your business about threats, GUARDIAN neutralizes attacks in real-time using AI-driven response systems.

✅ Fully Managed 24/7 Security Operations Centre (SOC)
GUARDIAN’s dedicated security analysts don’t just monitor threats—they actively eliminate them before they escalate.

✅ Advanced Endpoint Detection & Response (EDR/XDR)
While SENTINEL provides basic security monitoring, GUARDIAN isolates infected devices, prevents ransomware spread, and stops malware before it executes.

✅ Dark Web Surveillance & Threat Intelligence Integration
GUARDIAN detects stolen credentials, insider threats, and leaked business data, giving you time to act before criminals do.

✅ Managed Firewall & Network Intrusion Prevention (IPS/IDS)
GUARDIAN includes advanced AI-powered Intrusion Prevention Systems (IPS), real-time traffic analysis, and automatic blocking of zero-day threats.

✅ Compliance & Risk Management
For businesses needing ISO 27001, GDPR, PCI-DSS, or NIST compliance, GUARDIAN provides quarterly risk assessments and compliance-driven security strategies.

✅ 4-Hour Incident Response SLA
SENTINEL offers continuous monitoring, but GUARDIAN guarantees an expert-led response within 4 hours, ensuring rapid containment and damage control.

⚠️ The True Cost of a Cyberattack

For SMBs and mid-sized enterprises, the cost of a cyberattack can be crippling, often leading to long-term business damage.

💰 Ransomware Attacks

SMBs and growing businesses face ransom demands of £50,000 – £200,000, plus forensic investigation and data recovery costs.

⏳ Operational Downtime

A cyberattack can shut down operations for days or weeks, leading to thousands in lost revenue per day.

📉 Reputation & Customer Trust Loss

A security breach can cause clients and partners to terminate contracts, resulting in long-term revenue decline.

⚖️ Regulatory Fines & Compliance Risks

Businesses handling customer or financial data face UK GDPR fines up to £17.5 million or 4% of annual turnover.

🚨 Legal Fees & Cyber Insurance Gaps

Most cyber insurance policies won’t cover all damages unless proper security controls were in place before an attack—making proactive cybersecurity essential.
