Your data, our responsibility: Building trust through secure operations

Outsourcing business processes means trusting someone else to represent your brand, deliver your service, and importantly, protect your customers’ data. That trust isn’t given lightly, and at Sigma Connected, we never take it for granted.

From financial services and utilities to insurance and telecoms, many of our clients operate in tightly regulated environments. We know that for them, data security is not just a requirement, it’s foundational. That’s why we’ve built a security and governance approach that prioritises responsibility, accountability, and continuous improvement.

Certified, audited, accountable

At the procedural level, Sigma Connected holds several leading certifications which independently verify the rigour of our controls. These include:

• ISO/IEC 27001 – Our information security management system (ISMS) is certified to this internationally recognised standard, covering governance, risk management, and operational security.
• Cyber Essentials and Cyber Essentials Plus – These accreditations validate our ability to defend against common threats and demonstrate strong cyber hygiene.
• PCI DSS – As a business processing cardholder data, we have achieved and maintained a formal PCI Report on Compliance (ROC), audited by qualified security assessors.
• SOC 2 (Type I) – Our systems and controls are assessed against AICPA’s trust service principles, providing assurance around security, availability, and confidentiality.

These aren’t just certificates on the wall. They’re a reflection of the systems and processes we’ve embedded into our operations, day in and day out.

A layered approach to security

Security isn’t a single solution. It’s a strategy. And ours is built on defence in depth. This means we deploy multiple, overlapping controls at every layer of our infrastructure and service delivery. If one layer is bypassed, others are still in place to protect systems and data.

This includes:

• Secure network architecture and segmentation
• Endpoint protection, detection, and response
• Access controls enforced through least privilege and multi-factor authentication
• Real-time monitoring and alerting through SIEM systems and our 24/7 Security Operations Centre (SOC)
• Encryption of data in transit and at rest
• Physical security at all office and data centre locations

We also conduct regular, independent penetration testing to validate the strength of our defences and simulate realistic attack scenarios.

People-first security: skilled, trusted, and empowered

Technology alone doesn’t make an organisation secure -people do. One of our greatest strengths is the calibre and commitment of the security professionals behind the scenes.

Our internal teams bring expertise across the full spectrum of information security: from ethical hacking and technical assurance, to compliance, auditing, policy development, and everything in between. These are not generic roles. They are specialists who understand the evolving threat landscape and the practical realities of keeping systems safe in complex, fast-paced environments.

They work closely with business units to ensure that security isn’t seen as a barrier, but as an enabler. Built in by design, not bolted on as an afterthought.

Ongoing training and awareness

We maintain high standards across all levels of the organisation. Every employee, regardless of role, completes mandatory security and data protection training during onboarding, with refresher modules delivered regularly throughout the year.

In addition to baseline training, we run:

• Phishing simulations and live feedback campaigns
• Workshops on secure handling of data for frontline and operations teams
• Deep-dive technical upskilling for engineers, developers, and administrators
• Scenario-based incident response exercises to test preparedness and response capability

Security isn’t left to a single team – it’s woven into the company culture.

Data governance and privacy by design

We treat client and customer data with the same level of care we’d expect for our own. Our data protection governance is fully aligned with the UK GDPR, supported by designated roles including a Data Protection Officer and internal audit function.

Our systems and practices are designed with privacy by design and by default principles:

• Data minimisation is applied wherever possible
• Access to personal data is tightly controlled and monitored
• Data retention and disposal are handled according to well-defined policies
• Client data is only ever processed for agreed purposes under strict contractual terms

We also support clients in navigating their own compliance requirements, providing evidence, assurance, and flexibility where required.

Operational resilience and incident preparedness

In today’s threat landscape, the ability to respond and recover is as important as prevention. We maintain a fully documented and regularly tested incident response plan, coordinated across IT, legal, data protection, and business operations.

All our employees are aware of how to report suspected incidents, and we have clear escalation paths in place. Where appropriate, we simulate real-world scenarios through tabletop exercises to build muscle memory and improve coordination.

Resilience is also built into our platform architecture, ensuring continuity, availability, and integrity even under pressure.

A commitment to continuous improvement

We don’t view security as a static checklist. Our approach is iterative, reflective, and constantly evolving. We actively monitor threat intelligence sources, regulatory developments, and industry trends so we can adjust and improve.

We conduct:

• Post-incident reviews, whether internal or industry-wide, to identify learning opportunities
• Internal audits and gap analyses ahead of formal assessments
• Client-specific control reviews, adapting to changing risk profiles where needed
• Quarterly strategy reviews at the leadership level focused solely on security posture

Our commitment is not just to meet standards, but to exceed them sustainably and without complacency.

Trusted by regulated clients

Sigma Connected is trusted by organisations that operate under close scrutiny. Many of our clients are subject to FCA, Ofgem, or public sector controls. They come to us not just for cost efficiency or operational scale, but because we provide a safe, dependable, and transparent operating environment.

We work in partnership with our clients’ compliance and risk teams to provide audit access, evidence packs, and controls assurance. For us, security and trust go hand in hand and we’re here to support your regulatory obligations, not add to them.

In summary

Trust is built on evidence, not promises. At Sigma Connected, we bring together certified systems, specialist people, and a layered, resilient security model to protect what matters most – your data and your reputation.

Whether you’re seeking a new BPO partner or re-evaluating your current risk landscape, we’d welcome a conversation. Because in a world of increasing complexity, you deserve the assurance that your partner is as serious about security as you are.
