Red Team Operations — London
Realistic Adversary Simulation for UK Organisations
Cyber Sentinel Solutions Ltd — London & Bristol, UK
Test how a real attacker would target your organisation — from phishing and social engineering to lateral movement, domain compromise and data exfiltration.
What Is a Red Team Operation?
A Red Team Operation goes far beyond a traditional penetration test. Instead of simply scanning for vulnerabilities, a Red Team simulates a real cyberattack against your organisation, using the same tactics, techniques and procedures (TTPs) that modern threat actors and ransomware groups use in the wild.
The aim is not just to find weaknesses in systems, but to answer critical business questions such as:
- Can an attacker gain an initial foothold in our environment?
- Can they move laterally and escalate privileges to domain admin or global admin in Azure?
- Can they access highly sensitive data or critical business systems?
- How long would they remain undetected?
- How effective are our SOC, EDR/XDR and incident response processes?
In other words: “Can we survive a modern, targeted cyberattack?”
Why London-Based Companies Need Red Teaming
London is one of the most targeted business hubs in Europe. Financial organisations, law firms, technology companies, healthcare providers and professional services firms are attractive targets for:
- ransomware groups
- state-sponsored actors
- industrial espionage
- advanced financial fraud campaigns
- supply-chain and third-party compromise
Common risk drivers we see in London and across the UK include:
- rapid cloud adoption (Azure, Microsoft 365) without full security hardening
- complex hybrid environments with legacy systems
- high-value confidential data (legal, financial, IP, personal data)
- regulatory pressure and cyber insurance requirements
A Red Team Operation provides real evidence of how prepared your organisation is for real-life attacks — not just compliance checklists.
Our Red Team Approach
Cyber Sentinel Solutions Ltd follows a structured, intelligence-led methodology aligned with industry frameworks such as:
- MITRE ATT&CK
- NCSC Adversarial Simulation guidance
- NIST SP 800-115
- TIBER-EU style threat-informed testing (where applicable)
Every engagement is tailored to your organisation’s threat model, industry, size and technology stack (on-premises, hybrid, cloud-first).
Red Team Operation — Phases
1. Reconnaissance & Intelligence Gathering
We start by mapping your digital footprint, using OSINT and threat intelligence techniques to identify:
- public exposure of domains, subdomains and services
- email formats and staff identities
- leaked credentials and dark web exposure
- cloud entry points and VPN/remote access paths
- third-party suppliers and potential weak links
This stage answers the question: “What can an attacker learn before they ever touch your network?”
2. Initial Access (Foothold)
We simulate realistic initial access scenarios, which may include:
- targeted phishing and spear-phishing campaigns
- credential harvesting and password spraying
- multi-factor authentication (MFA) weaknesses
- exploitation of misconfigurations in web, VPN or remote access portals
- cloud-focused attacks against Azure AD / Microsoft 365 accounts
The objective is to obtain a controlled foothold while maintaining strict safety and legal boundaries.
3. Privilege Escalation
Once inside, the Red Team attempts to gain higher privileges by exploiting:
- Active Directory misconfigurations
- weak service accounts and delegation paths
- Kerberoasting and AS-REP Roasting opportunities
- token theft and impersonation
- privilege escalation paths in Azure AD and Microsoft 365
We answer: “How quickly can an attacker move from a single compromised account to domain or global admin?”
4. Lateral Movement
We test how easily an attacker can move deeper inside the environment, including:
- pivoting through RDP, SMB and remote execution mechanisms
- identifying and abusing trust relationships between systems
- moving between on-premises and cloud resources
- discovering high-value targets such as domain controllers and management servers
This stage reveals segmentation gaps and weak identity boundaries.
5. Objective-Based Attack Scenarios
Every engagement is built around clear, business-relevant objectives, for example:
- compromise of a C-level mailbox (CEO fraud / BEC scenario)
- access to highly confidential legal or financial documents
- simulated ransomware deployment readiness assessment
- exfiltration of sensitive data (customer, patient or IP)
- compromise of Azure subscription resources or critical SaaS platforms
We do not cause operational damage — but we demonstrate how real attackers would attempt to achieve these objectives.
6. Detection & Response Testing
A key goal of the Red Team Operation is to measure your detection and response capability:
- Are EDR/XDR tools triggering alerts?
- Is the SOC correlating the activity correctly?
- Are incident playbooks activated in time?
- Are suspicious events escalated to the right people?
We track dwell time: How long can an attacker remain in your environment before being noticed?
7. Reporting, Evidence and Executive Briefing
You receive a complete set of deliverables, typically including:
- Executive summary for leadership and board
- Detailed technical report with all paths, findings and evidence
- MITRE ATT&CK mapping of observed techniques
- prioritised remediation roadmap
- optional workshop or live walk-through for stakeholders
The objective is not to shame or blame — but to provide clear, actionable insight into your real security posture.
Who Is This Service For?
Red Team Operations are ideally suited for organisations that:
- handle sensitive legal, financial, health or personal data
- operate in regulated sectors or under strict compliance regimes
- are based in London or other major UK cities with high risk exposure
- have already implemented basic security controls and want to test them under realistic conditions
- need evidence for boards, regulators or insurers that defences are tested in practice
Typical clients include:
- law firms and professional services
- financial institutions and fintechs
- healthcare and life sciences
- technology and SaaS providers
- retail, e-commerce and logistics
- manufacturing and industrial organisations
