Security Architecture & Controls
A policy can say who should have access. Your systems must enforce it. Review identities, permissions and technical controls to reduce unnecessary access and the spread of an attack.
Review identities, administrator access and network boundaries. Build practical controls across cloud and on-site systems to make unauthorised access harder.
Why this matters
Security architecture is how protection is built into the systems you use. For financial firms, the design must consider customer records, payment services and powerful accounts. We check how systems connect and who can reach them, then help reduce the routes an attacker could use.
Extended Detection and Response, or XDR, connects warning signs from devices, accounts and other systems. It helps teams investigate activity that may otherwise look unrelated.
We review how the tools are set up and how staff use the results. The value comes from better decisions and response, not simply owning the software.
Privileged Access Management, or PAM, protects accounts that can make major changes. Administrator access can expose far more than an ordinary user account.
We help limit who receives it, how it is approved and how it is monitored. Temporary access and regular reviews can reduce unnecessary exposure.
Identity and Access Management, often shortened to IAM or IDAM, links access to a person’s role. It includes joining, changing roles and leaving the organisation.
We help remove outdated permissions and strengthen sign-in checks. Staff should have the access they need to work, with clear approval for anything more.
Network segmentation means separating parts of your systems. It can make it harder for an attacker who reaches one area to move into another.
We review the links around important services and data. The design should support legitimate work while reducing the impact of a compromised account or device.
Requirements depend on your regulated activities, the data you use and where you operate. We work with your security, risk and compliance teams to turn the relevant duties into actions, owners and evidence.

Extended detection and response, or XDR, brings signals from different security tools together. A suspicious sign-in and unusual device activity may be more useful when investigated as one event.
How we help
We help use Microsoft Defender XDR to connect protection across identities, endpoints and cloud systems. The work focuses on useful detections, clear investigation steps and agreed responses.
Your team can follow related activity across systems, with less need to piece everything together manually. Coverage still depends on the systems connected and how the tools are run.
Discuss your prioritiesPrivileged access management, or PAM, controls high-level access. An administrator account may be able to change settings, create users or reach information that most staff cannot see.
How we help
We help strengthen sign-in checks, manage privileged sessions and review when powerful access is needed. Multi-factor authentication adds another check beyond a password. Session monitoring helps show what happened.
The aim is to limit unnecessary access and make sensitive actions more accountable, reducing the damage a stolen or misused administrator account could cause.
Discuss your prioritiesIdentity and access management means checking who someone is and deciding what they can use. Access can become outdated when staff change jobs, suppliers change or people leave.
How we help
We help review permissions and apply identity controls, including relevant CyberArk integrations. Access should match a clear business need, with approval and review steps that teams can follow.
Your organisation gets a more reliable way to manage access throughout its life, helping protect customer information without making everyday work unnecessarily difficult.
Discuss your prioritiesNetwork segmentation divides a network into controlled areas. If an attacker reaches one device, it should not automatically give them an easy route to customer records or important systems.
How we help
We help review how systems connect and where stronger boundaries are needed. Access between areas should support real business tasks, with checks around sensitive systems and information.
The result is a clearer design for limiting movement through the organisation. It supports containment, while keeping the connections that essential services need to operate.
Discuss your prioritiesHow we help
Build on the work you already have. Focus effort where it can make the most useful difference.
Map how users, devices, applications and networks connect. Look closely at customer data, powerful accounts and the links that could let a problem spread. Review the design against how the business actually works. This helps identify unnecessary access, weak boundaries and missing safeguards. The findings should explain the likely impact and the improvements needed, so teams can make informed design decisions.
Bring relevant warning signs together across identities, devices and cloud systems. Microsoft Defender XDR can help link related activity that separate tools might show as isolated alerts. Configure the connections and detections around the environment, then check how the team will investigate and respond. The aim is a clearer picture of a developing incident, with enough context to decide what needs action.
Review who has powerful permissions and why they need them. Stronger sign-in checks, managed privileged access and time-limited permissions can reduce unnecessary exposure. Use appropriate tools and processes to record sensitive sessions and support access reviews. Keep the approval and removal steps clear as people change roles or leave. This helps limit the damage a compromised or misused account could cause.
Separate sensitive systems from areas that do not need unrestricted access. Hardening means reducing weaknesses through safer settings and tighter control of unnecessary features or connections. Apply these changes around the systems that matter most, while checking that important services still work as intended. Clear boundaries and stronger settings help limit an attacker’s options if one part of the environment is compromised.
