Our Cyber Security Consulting Approach

A structured approach to cyber security consultancy ensures security projects align with wider business goals. At Stripe OLT, our consultancy process focuses on understanding risks, meeting compliance requirements, and implementing measures that mitigate threats effectively. Some engagements are purely advisory, while others involve full delivery. Here, our approach flexes to meet your organisation’s needs.

Assess

Every engagement starts with understanding your specific cyber security needs — whether that’s strengthening your defences against cyber threats, aligning with compliance frameworks like ISO 27001 or Cyber Essentials Plus, improving incident readiness, or securing a cloud environment. We assess your current state, risks and security challenges to create a clear security brief.

Plan
With your goals and current security landscape understood, we create a practical plan. This could be a compliance roadmap, a Zero Trust strategy, a security operations improvement plan or a phased remediation programme to fix vulnerabilities.

Implement
Where delivery is required as part of the engagement, we execute the plan with minimal disruption. Whether it’s implementing security in Microsoft 365, deploying advanced detection tools or improving identity and access controls, we manage the process and document every step.

Support
Post implementation, we provide expert guidance to keep the momentum. This might be ongoing vCISO advisory, periodic security reviews or supporting your in-house team with specialist expertise to keep risk under control.

Evolve

Your security strategy shouldn’t be static. We’ll monitor changes in your business, industry regulations and the wider threat landscape to ensure your defences are effective. Whether that means updating compliance controls, tuning detection rules or adopting new security tools, we’ll make sure your cyber security posture keeps pace with emerging threats.

Managed Cyber Security FAQs

What does a cyber security consulting firm do?

A cyber security consulting firm helps organisations understand their risk, strengthen defences, and build resilience against today’s evolving cyber threats. Unlike off-the-shelf security tools or packaged services, consultancy isn’t one-size-fits-all. Instead, consultants work alongside your business to develop a tailored strategy that reflects your size, industry, compliance needs and threat landscape.

Typical services include:

Assessing your current security posture through risk assessments, audits and penetration testing
Designing and implementing controls to protect critical systems, data, and users
Advising on regulatory compliance such as ISO 27001, GDPR and Cyber Essentials Plus
Supporting incident response planning and recovery strategies
Providing ongoing strategic guidance to keep you ahead of new threats

At Stripe OLT, our consultants combine real-world technical expertise with industry knowledge to deliver practical, actionable advice, whether you’re looking to achieve compliance, reduce risk, or transform your wider IT and security operations with cutting-edge technology.

How do I engage with a cyber security consultancy?

Engaging with a cyber security consultancy usually starts with understanding your current challenges and goals. From there, consultants can help you scope the right level of support, whether that’s a one-off risk assessment, a penetration test, or a long-term strategy for improving your overall security posture.

Engagements can involve:

Discovery & assessment: reviewing your existing systems, risks and compliance needs to identify potential vulnerabilities
Defining objectives: aligning security measures to your business goals and industry needs
Tailored recommendations: creating a clear plan of action, from technical controls to governance frameworks
Implementation support: helping you roll out effective measures such as MFA, incident response plans, security controls and security monitoring
Ongoing partnership: Providing continuous guidance to help you stay ahead of the latest threats and adapt as they evolve

At Stripe OLT, we start every service delivery with a clear conversation about your environment and objectives, then shape a consultancy plan around your risk profile and compliance needs. If you’re ready to take the first step, get in touch with our team to discuss your requirements.

How can cyber security consultancy services help with cyber resilience?

Cyber resilience is about more than just preventing attacks; it’s about ensuring your organisation can withstand, respond to, and recover quickly from them. Cyber security consultancy companies help organisations take a proactive approach, by strengthen resilience through identifying risks early, putting the right controls in place, and preparing your teams to respond effectively.

Some key areas include:

Risk assessments: regular reviews via services such as pen testing to identify potential vulnerabilities and mitigate risks before attackers can exploit them
Resilient controls: Where businesses can implement measures such as multi-factor authentication, secure configuration management, and ongoing monitoring
Incident response: developing and testing plans so you can minimise disruption and recover quickly when an attack occurs
Ongoing improvement: adapting your security strategy to stay ahead of the latest threats and industry compliance requirements

At Stripe OLT, we help businesses strengthen their cyber resilience, combining consultancy expertise with additional practical implementation so you can operate with confidence even in the face of evolving cyber threats.

What compliance areas can cyber security consultancy services help with?

Meeting compliance requirements is now a critical part of running a secure and trusted business. Falling short can mean regulatory fines, loss of customer confidence, and even missed opportunities to win contracts. Cyber security consultancy services help you understand which standards apply to your organisation, guide you through the process, and put the right measures in place to achieve and maintain compliance.

Common areas include:

ISO 27001: Is a standard that proves that organisations have implemented international best practice for information security management systems
Cyber Essentials & Cyber Essentials Plus: These are UK government-backed standards that demonstrate your business has strong baseline cyber security controls in place, often a requirement in both public sector and private supply chains.
GDPR: The need to ensure personal data is handled securely and in line with European and UK data protection laws and regulations
Sector-specific compliance: Niche regulatory standards in areas such as finance, healthcare or legal, where additional frameworks and certifications are often mandatory

At Stripe OLT, we help organisations achieve compliance not just as a tick-box exercise, but as part of a wider cyber security strategy, strengthening your security posture, protecting data, and demonstrating trust to your clients and partners.
