Managed security services that strengthen your Microsoft cloud
From identity and access to endpoint protection and threat detection, Harrby helps you reduce risk across your Microsoft 365 and Azure environments.
We design and run practical security controls using Microsoft security tools so your organisation is better protected against modern attacks without blocking staff from doing their jobs.
Improve your security posture without overwhelming your team
Our managed security services focus on achievable, high value controls that make a real difference to your risk profile.
Stronger protection for identities and access
Reduce the risk of account compromise with multi factor authentication, conditional access and better protection of privileged roles.
Better visibility of threats and risky activity
Bring together signals from Microsoft security tools so you can see what is happening across identities, endpoints and cloud services.
Fewer gaps between cloud and on premises
Align security controls across Microsoft 365, Azure and remaining on premises systems so attackers have fewer weak points to exploit.
Security that fits how your organisation works
Apply controls that respect the way staff, contractors and partners work so security becomes part of the workflow, not an obstacle.
Faster and more consistent response to alerts
Define who does what when a security alert is raised so issues are handled consistently instead of on a best effort basis.
A clear and evidence based security story
Give executives and auditors clear information about what is in place, what has improved and what is planned next.
What we manage in Microsoft security
We focus on practical use of Microsoft security tools to protect identities, devices and cloud workloads.
Identity and access protection
Configuration and tuning of multi factor authentication, conditional access, sign in risk and protection of privileged accounts.
Endpoint security with Microsoft Defender
Defender for Endpoint policies, onboarding, attack surface reduction rules and basic investigation workflows for devices in scope.
Email and collaboration security
Defender for Office 365 configuration including anti spam, anti phishing, safe links and safe attachments policies.
Security monitoring and alerts
Setup and tuning of alerts from Microsoft 365 Defender and Azure security services so important events are highlighted to the right people.
Security baselines and hardening guidance
Alignment with Microsoft security baselines and recommended hardening for core Microsoft cloud services and endpoints.
Security operations run book and workflows
Definition of response steps for common scenarios so incidents are managed in a repeatable and auditable way.
Regular posture reviews and recommendations
Periodic reviews of security posture with clear recommendations for next steps and prioritised improvements.
The Harrby difference for security
We focus on achievable, well documented improvements that fit the reality of your organisation instead of chasing checklists or one off projects.
Security that respects operations
We design controls with input from IT, business and risk teams so security improves without bringing day to day work to a halt.
Experience with Essential Eight and Microsoft baselines
We understand how to apply Essential Eight and Microsoft security baselines in real environments rather than only on paper.
Clear documentation and evidence
We produce configuration records, diagrams and change history that support risk, audit and compliance conversations.
Advisory and operations together
You get help with strategy and design as well as the ongoing management needed to keep security controls effective.
Plain English communication with stakeholders
We explain threats, options and trade offs in language that technical and non technical stakeholders can use.
Security managed services frequently asked questions
Common questions organisations ask when they are considering managed security services for Microsoft cloud.
Do you replace our existing security team or work alongside them
We can do both. Some organisations rely on Harrby as their main Microsoft security partner, while others ask us to support and extend an internal security or IT team.
Which Microsoft security tools do you work with
We focus on Microsoft 365 Defender, Defender for Endpoint, Defender for Office 365 and core Azure security capabilities, and we can integrate with other tools where needed.
Can you help us move towards Essential Eight maturity targets
Yes. We can map security controls in Microsoft cloud to Essential Eight strategies, identify gaps and help plan the work needed to move towards a target maturity level.
Do you provide a full security operations centre
We focus on Microsoft security configuration, monitoring and practical response workflows. If a full 24 by 7 SOC is required, we can work alongside a specialist provider.
How do you handle alerts and incidents in practice
We agree on priorities, response steps and communication paths up front, then use that run book when alerts or incidents occur so there are no surprises.
Can you support both cloud only and hybrid environments
Yes. We work with cloud first organisations as well as customers who still have important on premises systems connected to their Microsoft cloud.
