The Pillars of a Modern Cyber Defence-in-Depth Strategy
A modern Cyber Security strategy recognises that no single technology, policy, or control can fully protect an organisation from today’s evolving threat landscape. Instead, it layers multiple aligned security measures across users, devices, networks, applications, and cloud workloads. This multi-layered approach ensures that even if one control fails or is bypassed, additional defences remain in place to detect, contain, and remediate the threat before it leads to business-impacting downtime or data loss.
At the foundation of this strategy is strong identity and access management. With attackers increasingly targeting user credentials, enforcing multi-factor authentication, robust password policies, and least-privilege access is essential. Paired with continuous monitoring and behavioural analytics, PurpleJelly can quickly identify unusual account activity and prevent compromises before they escalate. Identity is now the new perimeter, and securing it is fundamental to any modern defence approach.
To stay ahead of modern hackers, your business needs a layered approach that protects every possible entry point. Here is how we safeguard your organisation:
Proactive Patching & Device Monitoring
An unpatched computer is an open door. Hackers frequently exploit known vulnerabilities in software that hasn’t been updated.
What we do: We handle all security patch management and device monitoring automatically. We ensure your operating systems and third-party apps are always up to date, closing security holes without interrupting your workflow.
Endpoint Protection with MDR (Managed Detection & Response)
Your laptops, workstations, and servers (endpoints) are the front lines of your network. Traditional antivirus only looks for “known” threats.
What we do: We provide Endpoint Detection and Response (EDR), but we take it a step further with Managed Detection and Response (MDR). This means 24/7 human-led monitoring. If a threat is detected at 2:00 AM, our security experts are already hunting it down and neutralising it before it can spread.
Microsoft 365 Managed Services: Secure, Compliant, and Resilient
Microsoft 365 is the engine of your business, but “out of the box” settings often leave gaps in security and data protection and securing it is complex. We manage the “behind-the-scenes” architecture of your Microsoft environment, hardening your configuration against threats to keep your teams productive and your data locked down.
Microsoft 365 Tenant Configuration & Compliance
Best-Practice Configuration: We implement industry-standard security baselines, including Multi-Factor Authentication (MFA) and Conditional Access policies.
Continuous Policy Monitoring: Security isn’t a “one and done” task. We proactively monitor your tenant for configuration drift and unauthorised changes.
Governance & Compliance: We ensure your data sharing settings and user permissions align with your internal policies and regulatory requirements.
Microsoft 365 Enterprise-Grade SaaS Backup
Many businesses don’t realise that Microsoft is responsible for the platform, but you are responsible for your data. We close that gap with automated, daily backups for your entire M365 suite.
Mailbox Protection: Rapid recovery for Exchange Online, protecting you against accidental deletions, malicious insiders, or ransomware.
OneDrive & SharePoint Recovery: Full point-in-time restores for your files and document libraries, ensuring business continuity if a sync goes wrong.
Infinite Retention Options: Unlike the standard 30-day “Recycle Bin” limit, our backups can be retained for years to meet legal and audit standards.
Microsoft 365 ITDR
Your Microsoft 365 environment contains your most sensitive data. Identity Threat Detection and Response (ITDR) is critical for stopping account takeovers.
What we do: We monitor your M365 tenant for “impossible travel” logins, unauthorised admin changes, and rogue apps. By securing the Identity (the user’s account), we ensure that even if a password is stolen, the attacker can’t gain a foothold.
Secure Email Protection: Blocking Phishing & BEC
Email remains the #1 vector for cyberattacks. Business Email Compromise (BEC) and sophisticated Phishing schemes often bypass traditional filters by using “social engineering” rather than malicious attachments.
What we do: We deploy advanced AI-driven email security that analyses sender behaviour and language patterns. This stops impersonation attempts and malicious links before they ever reach your employees’ inbox.
Managed Security Awareness Training – SAT
We provide practical, engaging training that teaches your team how to recognise phishing emails, social engineering scams and other risky online behaviours before they cause damage. It is powered by current expert threat intelligence with real-world examples delivering simulated phishing messages and easy-to-understand guidance. Your staff will learn exactly what to click, what to avoid, and when to report suspicious activity allowing your teams to build confidence as the human firewall.
Real-World Simulations: We use current threat intelligence to deliver “spot the red flag” phishing simulations that mimic actual modern attacks.
Role-Based Learning: Training is tailored to specific roles, ensuring the content is relevant, engaging, and never a waste of time.
Zero Disruption: Training sessions are short and impactful that fit into a busy workday.
A Culture of Safety: We move beyond “don’t click” to teach the why and how, building a confident, security-conscious culture where reporting threats becomes second nature.
DNS & Web Browsing Protection
Many attacks happen simply by a user visiting a compromised website.
What we do: Our DNS-level protection acts as a “security guard” for the internet. It blocks access to malicious domains and phishing sites in real-time, whether your employees are in the office or working remotely regardless of location.
