At telanova, we believe technology should empower organisations, not overwhelm them. That’s why we take a proactive, compassionate, and quality-driven approach to supporting Microsoft 365 Defender for our clients.
As a UK-based managed service provider supporting small and medium-sized businesses, security is never an afterthought. Microsoft 365 Defender plays a critical role in protecting users, devices, and data - and we ensure it’s configured, monitored, and maintained properly.
Proactive Support: Keeping Threats at Bay
Our approach to Microsoft 365 Defender is proactive, not reactive. We don’t wait for incidents to escalate - we actively monitor alerts, threat intelligence, and behavioural signals to reduce risk before it impacts your business.
We configure Defender policies based on each organisation’s size, risk profile, and compliance requirements, striking the right balance between strong protection and minimal disruption for users.
- Continuous monitoring of Defender alerts and security signals
- Threat investigation and rapid response
- Tailored Defender configurations aligned with real-world business use
Administration: Expert Configuration & Management
Microsoft 365 Defender is powerful, but only when configured correctly. Poorly tuned policies can either leave gaps in security or frustrate users with unnecessary blocks.
Our team handles all aspects of Defender administration, including:
- Policy configuration: Anti-malware, anti-phishing, endpoint detection and response (EDR), and attack surface reduction rules.
- User & device management: Using tools like Microsoft 365 Lighthouse, we apply security baselines and monitor for unusual behaviour.
- SIEM integration: Where required, Defender alerts can be integrated with SIEM platforms for enhanced visibility and incident correlation.
This ensures Defender works as part of a wider, well-managed security strategy rather than in isolation.
Maintenance: Continuous Improvement & Compliance
Security is never “set and forget”. Threats evolve constantly - and so must your defences.
We maintain Microsoft 365 Defender through:
- Regular security reviews: Auditing policies and reviewing threat reports to adapt to emerging risks.
- Patch & update management: Ensuring Defender components and supporting systems stay up to date.
- Compliance alignment: Supporting best practices aligned with UK guidance such as NCSC recommendations.
- User awareness: Reinforcing security through training to help staff recognise phishing and social engineering attacks.
This ongoing care helps reduce vulnerabilities while maintaining a secure and compliant environment.
Partnership, Transparency & Trust
We don’t see ourselves as a third-party supplier - we act as an extension of your team.
That means clear communication, transparent reporting, and honest advice. Our clients receive regular insights into their security posture, and we’re always available to explain alerts, risks, or recommended changes in plain English.
With telanova, Microsoft 365 Defender becomes a reliable layer of protection - not another system you have to worry about.
Frequently Asked Questions
What does Microsoft 365 Defender protect?
Microsoft 365 Defender protects users, devices, email, identities, and cloud apps using threat detection, prevention, and response capabilities.
Is Microsoft Defender enough on its own?
Defender is a strong foundation, but it must be properly configured, monitored, and maintained to be effective. That’s where managed support makes a real difference.
Do small businesses really need Defender monitoring?
Yes. SMEs are frequently targeted because attackers assume weaker security. Active monitoring significantly reduces the risk of breaches.
Will Defender slow down users?
When configured correctly, Defender operates quietly in the background with minimal user impact.
Is Defender included with Microsoft 365?
Basic protection is included with many plans, while advanced Defender features require Business Premium or Enterprise licences.
