Overview

Basic antivirus is not enough anymore. Cyber criminals are getting more sophisticated. Ransomware attacks happen faster. Business email compromise schemes are harder to spot. And when an attack happens at 3am, an automated alert is not enough. You need a real person who can help.

SMEs need advanced security too. You face the same threats as larger organisations. You just need security that is designed for your size and budget.

At Dark Knight, we provide enterprise-level protection delivered by real people. Our Managed Detection and Response (MDR) service combines 24/7 Security Operations Centre (SOC) monitoring with human analysts who know how to spot threats and stop them fast.

  • We catch ransomware before it encrypts your files
  • We detect compromised accounts before attackers can steal your data
  • When something serious happens, you will speak to an actual security professional - not a voicemail

This page covers our advanced security services: 24/7 monitoring and threat detection, vulnerability management, penetration testing, email security, and security awareness training.

SIEM, MDR & 24/7 SOC Monitoring

There is a big difference between having security tools and having active defence.

Tools send alerts. Active defence means having experts who watch for threats, investigate suspicious activity, and take action to stop attacks before they succeed.

That is what our 24/7 Security Operations Centre does.

Real Human Support - 24/7

When you get a security alert at 3am on a Sunday, you should not have to figure it out alone. You should not get an automated response or a ticket number telling you someone will look at it Monday morning.

You need a real security professional. Right now.

Our 24/7 SOC gives you access to a real security professional on the phone, any time:

  • No call centres or automated responses during critical incidents
  • Immediate human assistance during suspected breaches, ransomware events, account compromise, or out-of-hours security alerts
  • Calm, professional guidance when internal IT and management are unavailable

This is designed so someone can respond at 3am when you need it most - reducing panic, downtime, and business impact.

Microsoft 365 & Google Workspace Breach Control

Most cyber attacks start with compromised cloud accounts. A stolen password, a successful phishing email, or multi-factor authentication fatigue attacks. Once attackers get access to your email or file storage, they can steal data, send fraudulent invoices, or spread malware to your contacts.

Our cloud breach control service provides continuous monitoring of Microsoft 365 and Google Workspace environments to catch attacks early.

Detection coverage:

  • Suspicious logins and impossible travel events
  • MFA fatigue or bypass attempts
  • Privileged account misuse
  • Token theft and session hijacking

Immediate containment actions:

  • Account lock-down and forced password resets
  • Session revocation
  • Privileged access restriction

MDR - Ransomware Protection

Ransomware moves fast. By the time you realise you have been infected, your files are already encrypted, and your backups may be corrupted. Traditional antivirus is not enough - it cannot stop sophisticated attacks that use legitimate tools or move laterally through your network.

A lightweight MDR agent is installed on in-scope devices, providing continuous monitoring for:

  • Ransomware behaviour and encryption activity
  • Malware and zero-day threats
  • Credential harvesting
  • Suspicious process execution

When threats are detected, our response is immediate:

  • Automatic isolation of infected devices to prevent spread
  • Blocking of malicious processes and command-and-control traffic
  • Human analyst verification before high-impact actions (where possible)
  • Escalation to phone-based support for confirmed ransomware activity

Integrated 24/7 Incident Handling

When a serious threat is detected, here is what happens:

  • 1.We activate automated controls to limit damage
  • 2.Our SOC analysts investigate and validate the threat
  • 3.We contact you by phone for high-severity incidents
  • 4.We give you clear guidance on what has happened, what has been contained, and what actions are required next
  • 5.We supply incident documentation and recommendations after the event

Our integrated incident handling combines technology and human expertise. You are never left trying to interpret security alerts on your own.

Scope covers approved users, devices, and cloud tenants only. Full ransomware remediation or forensic investigation may require a separate incident response engagement.

Vulnerability Management - Internal & External

You cannot fix security problems you do not know about. Attackers are looking for vulnerabilities like unpatched software, misconfigured systems, weak passwords, and open ports.

Our vulnerability management service identifies and reduces security weaknesses across your internal network and internet-facing systems using enterprise-grade Qualys security scanning technology and experienced security engineers.

We offer the service in flexible tiers, allowing you to choose between visibility only or fully managed remediation.

Vulnerability Scanning & Remediation Guidance

What is included:

  • Internal and external vulnerability scanning
  • Deployment of Qualys cloud agents and/or virtual scanning appliances
  • Risk-based vulnerability detection and prioritisation
  • Clear, monthly reporting suitable for management and compliance

Service Options

Report-Only Vulnerability Scanning - Ideal for organisations with in-house IT teams:

  • Monthly vulnerability scans
  • Executive and technical reports
  • Optional Cyber Essentials/CE+ alignment

Managed Vulnerability Remediation - For organisations that want vulnerabilities actively resolved:

  • Monthly Qualys security scanning and reporting
  • A defined number of remediation guidance hours per month
  • Hands-on fixing by Qualys-experienced Windows and macOS engineers
  • Continuous improvement of your security posture

Penetration Testing Services

While vulnerability scanning tells you what is weak, penetration testing tells you what is actually exploitable.

Our penetration testing service provides controlled, ethical hacking security testing to identify exploitable weaknesses in your systems before attackers do. All testing is fully scoped, authorised, and conducted in line with recognised industry standards.

Internal Penetration Testing

Focused on risks that exist inside the organisation, including those from compromised user accounts or insider threats.

Testing coverage:

  • Internal network and infrastructure assessment
  • Active Directory security and permissions
  • Lateral movement opportunities
  • Privilege escalation paths
  • Identification of misconfigurations, weak controls, and excessive access

We perform testing from an assumed breach position to reflect real-world attack scenarios. Because most breaches start with one compromised account, not an external hack.

External Penetration Testing

Simulates attacks from the internet against your publicly accessible systems.

Testing coverage:

  • External IP addresses
  • Firewalls and perimeter controls
  • Remote access services (VPN, RDP, web portals)
  • Identification of exposed services, vulnerabilities, and misconfigurations
  • Validation of patching and hardening effectiveness

Infrastructure & Application Testing

Infrastructure Testing:

  • Servers, network devices, firewalls, and core services
  • Operating system and service-level vulnerabilities
  • Authentication, access control, and segmentation testing

Application Testing:

  • Web applications, portals, and APIs (where scoped)
  • Authentication and session handling weaknesses
  • Input validation and common attack vectors (OWASP Top 10)

Application testing is only included where explicitly defined in scope.

Reporting & Remediation Guidance

After any testing, you will receive:

  • Clear, prioritised findings based on real-world risk (not just CVSS scores)
  • Evidence-based reporting with reproduction steps
  • Practical remediation guidance suitable for IT teams and management
  • Optional executive summary for non-technical stakeholders

All testing is pre-scoped and formally authorised before engagement. Testing is conducted in line with recognised methodologies (CREST-aligned, OWASP, NIST principles).

Remediation work is not included unless stated in a separate agreement. Retesting and validation are available as an optional add-on.

Email Security

Email is still the most common way attackers get into businesses. Phishing emails that look like they are from your CEO, fake invoices from suppliers, attachments that install malware, or spoofed domains that impersonate your company.

Our email security service is designed to protect your organisation from email-based threats such as phishing, impersonation, spoofing, and malware.

Advanced Email Threat Protection

What is included:

  • Phishing and malware detection to block malicious emails before they reach users
  • Impersonation protection to prevent attackers posing as executives, staff, or trusted suppliers
  • Spoofing prevention to stop unauthorised use of your domain
  • Digest assistant providing users with a safe, centralised view of quarantined messages
  • Policy-based filtering to reduce spam and business email compromise (BEC) attempts

Email Authentication & Trust

Proper email authentication stops attackers from impersonating your domain and improves your email deliverability.

  • SPF (Sender Policy Framework) - Makes sure only authorised systems can send email on behalf of your domain
  • DKIM (DomainKeys Identified Mail) - Validates message integrity and confirms emails have not been altered in transit
  • DMARC - Enforces domain protection policies and provides visibility into spoofing and misuse
  • TLS (Transport Layer Security) - Encrypts email in transit between mail servers, where supported

Security Awareness Training

Your team is either your strongest defence or your weakest link. Security awareness training helps them recognise threats and make better decisions.

We deliver industry-leading security awareness training designed to reduce human risk and support compliance requirements.

User Security Training

We provide training as part of a managed support contract or as a standalone Dark Knight subscription. Content is tailored to your industry, risk profile, and user roles.

Training covers:

  • Password hygiene and MFA
  • Email and social engineering threats
  • Data protection and safe handling of information
  • Remote and hybrid working risks

Phishing Awareness & Testing

We reinforce this training through ongoing phishing awareness and testing:

  • Simulated phishing campaigns to assess user susceptibility and reinforce safe behaviour
  • Education-led approach where users who fail simulations receive targeted follow-up training
  • Phishing results used to identify high-risk trends and areas requiring additional focus

Training covers security awareness, not formal technical certification. Periodic training sessions are delivered via online learning modules, automated campaigns, and targeted refresher training.
