Job Overview

Trident is a UK based Managed Service Provider (MSP) helping organisations protect what matters. As cyber threats evolve, we are expanding our dedicated security team to strengthen our managed security services and build new offerings that further protect our clients’ businesses. We’re looking for a Security Consultant to play a pivotal role in this mission within our Security & Compliance team.

As a Security Consultant, you will work alongside experienced security professionals to develop, enhance, and deliver managed security services, ensuring our customers remain secure and compliant. This role is ideal for someone who thrives in a fast-paced MSP environment and enjoys making a tangible impact on security posture across multiple clients. You’ll have the opportunity to build services in areas like threat detection, vulnerability management, and compliance, while working consultatively with colleagues and clients to improve security outcomes.

Key Responsibilities

XDR (Detection & Response): Working extensively on our Extended Detection and Response platform, including deployment, alert tuning, triage workflows, automation, and reporting. Continuously refine detections and playbooks to measurably improve threat detection and incident response times.

Cyber Essentials (Continuous Compliance): Help transform Cyber Essentials from a point-in-time certification into a year-round managed compliance service. Automate evidence collection and proactive remediation, deliver regular compliance reporting, and ensure clients remain compliant throughout the year. Work with account managers to promote adoption of this service, demonstrating its value over traditional one-off audits.

Security Assessments & Guidance: Support security assessments and reviews for clients and provide practical remediation guidance aligned with industry best practices and each customer’s risk profile.

Service Maturity & Tooling: Ensure our managed security services remain robust, effective, and aligned with best practices. Continuously review and improve the configuration and performance of our security tools, enhance data quality and alerts, and refine processes to increase efficiency and scalability. Introduce automation to eliminate repetitive tasks and reduce human error.

Patching & Vulnerability Management: Drive patch compliance across servers and endpoints, coordinating maintenance windows for updates with minimal disruption. Manage the end-to-end vulnerability remediation lifecycle – from discovery and prioritisation to remediation and verification.

Security Baselines & Awareness: Support our baseline policy enforcement and security awareness services. Work with service owners of inforcer (security baseline enforcement) and KnowBe4 (phishing simulation and security awareness training) to ensure baseline configurations remain in place and to mature these offerings over time.

Vulnerability Intelligence: Act as the internal vulnerability intelligence lead. Monitor newly disclosed vulnerabilities (CVE notices) that could impact our technology stack or client environments. Communicate relevant vulnerabilities internally with clear risk context and recommended actions. Plan and coordinate remediation—leveraging automation and existing tools (e.g. ConnectWise, Microsoft) or working with team members as needed. Help develop reporting to track risk trends and where required present vulnerability metrics to leadership and customers.

Future Service Development: Contribute to the design and rollout of new security services and advanced solutions as our portfolio grows. Partner with security consultants, technical operations, and the service desk to pilot and launch offerings that address evolving client needs.

Tools & Technologies

You’ll work with a wide range of security tools and platforms, including:

• Microsoft, ConnectWise, Kaseya and N-able.
• Dell, Fortinet, SonicWall and Cisco.
• SentinelOne, Bitdefender and DNSFilter.
• Auvik, inforcer, VulScan.
• Security awareness and phishing simulation platforms such as KnowBe4.

Experience with any of these or similar tools is a plus, but a willingness to learn and adapt is most important.

What you’ll bring

• MSP experience: You’re comfortable juggling priorities across multiple customers.
• Security fundamentals: Hands-on experience in vulnerability management, endpoint protection/XDR, patching, and security hardening.
• Service mindset: You care about outcomes, SLAs and customer communication—not just technology.
• Attention to detail: From alert tuning to evidence collection, you sweat the details.
• Collaboration: You work well with consultants, engineers, service desk and account managers, and you can explain security in plain English.

Nice to have (or a development plan to get there)

• Microsoft security certifications (e.g., SC200, SC300, SC400) or relevant industry certs (Security+, CISSP, vendor accreditations).
• Experience turning standards like Cyber Essentials into continuous compliance services.
• Exposure to automation/scripting to eliminate repetitive work.

How success will be measured

• Patch compliance across servers and endpoints.
• Vulnerability remediation against agreed SLAs.
• Baseline compliance across client environments.
• Reduction in client risk posture over time.
• Clean execution of maintenance windows.
• Accuracy/timeliness of onboarding & offboarding.
• Number and impact of automation initiatives.
• Clear, timely internal communications.

• A growing security practice where you can shape services and see your impact across diverse organisations.
• A collaborative culture, modern tooling, and support for continuous learning and certification.
• Influence company-wide service strategy and client experience.
