Check Point Software Technologies and UK-based managed security services provider SEP2 reported on June 24, 2026, that demand for specialist managed security providers (MSSPs) is accelerating sharply, fuelled by healthcare, public sector and other highly regulated organisations seeking deeper operational integration across hybrid environments, SASE, email security and AI-driven threats. The announcement underscores a fundamental shift away from generalist security outsourcing toward providers that can deliver granular, domain-specific expertise.
Specialist MSSPs are no longer a niche. They are becoming the central nervous system for organisations drowning in complex, multi-vendor security stacks. According to Check Point and SEP2, the combination of hybrid infrastructure, cloud adoption and the proliferation of AI-powered attacks has rendered traditional managed security models inadequate. What healthcare trusts, local governments and regulated industries now demand is operational depth – the ability to not just monitor alerts but to fine-tune policies, orchestrate responses and continuously harden environments in lockstep with evolving threats.
The Specialist MSSP Surge: What’s Driving It?
The past two years have seen a dramatic escalation in both the volume and sophistication of cyberattacks. Ransomware gangs have industrialised their operations; nation-state actors have turned AI into a reconnaissance and payload-generation engine; and the attack surface has ballooned with every new SaaS application, IoT device and home-office connection. Generalist MSSPs, which typically operate from a security operations centre (SOC) with broad but shallow tool coverage, can no longer keep pace.
Check Point and SEP2 point to three converging pressures that are pushing organisations toward specialists. First, regulatory environments such as the UK’s GDPR, the EU’s NIS2 Directive and sector-specific frameworks like the NHS Digital’s Data Security and Protection Toolkit create a compliance burden that demands continuous, auditable security postures. Second, the shift to hybrid work has made identity the new perimeter, forcing a rethink of how access is governed across on-premises, cloud and SaaS resources. Third, the weaponisation of generative AI has enabled attackers to craft hyper-personalised phishing emails, deepfake voice calls and adaptive malware that evades signature-based detection.
“What we’re seeing is a market that no longer wants a ticket-logger; they want a partner who lives inside their policy engine,” said Deryck Mitchelson, Field CISO at Check Point Software, during a joint briefing. “Healthcare organisations can’t afford to wait six hours for an analyst to triage a phishing alert. They need real-time, AI-assisted triage that understands clinical workflows.” SEP2’s CEO, Paul Starr, emphasised that public sector bodies often lack the internal bandwidth to manage a zero-trust architecture end-to-end. “It’s not about throwing more people at the problem. It’s about injecting operational intelligence – automating the mundane, escalating the critical and ensuring that every change is audit-ready.”
Hybrid Security: The Complexity Tax
Hybrid environments – a mix of on-premises data centres, multiple public clouds and edge locations – have become the default for most enterprises. Yet each platform comes with its own security model, logging format and configuration syntax. A specialist MSSP bridges these silos, translating disparate signals into a unified security narrative. For example, in a healthcare setting, a specialist might correlate an anomalous login to a cloud-hosted electronic health record system with a suspicious file download on a nurse’s workstation, triggering an automated lockdown before patient data is exfiltrated.
Check Point’s Infinity architecture, which underlies much of the company’s MSSP partner proposition, provides that cross-platform visibility. SEP2 has built its service around deep integration with Infinity, extending it with custom playbooks tailored to NHS trusts, local councils and regulated law firms. The result is not just monitoring but proactive hardening: continuously assessing configurations against benchmarks like CIS Controls, identifying drift and auto-remediating misconfigurations without disrupting clinical or operational services.
SASE and Zero Trust: From Buzzword to Operational Reality
Secure Access Service Edge (SASE) converges networking and security into a cloud-delivered fabric. It sounds elegant on a whiteboard, but operationalising it is fraught with complexity. Identity providers must be synchronised with cloud access security brokers (CASBs), web gateways, firewall as a service (FWaaS) and endpoint posture checks. A specialist MSSP that has already navigated hundreds of migrations can compress a 12-month SASE rollout into a quarter while avoiding the blind spots that lead to breaches.
SEP2 has carved a niche by wrapping SASE deployments in a managed service that includes continuous policy tuning. One NHS Trust, for example, discovered that its hastily deployed zero-trust network access (ZTNA) blocked clinicians from accessing patient records during ward rounds because device posture checks failed on shared workstations. SEP2’s analysts identified the issue within minutes and created a conditional access exception that maintained security while ensuring care was not delayed.
“Zero trust is not a product; it’s an ongoing discipline,” Mitchelson said. “A generalist MSSP will monitor alerts; a specialist will adjust the policy baseline every week as new devices, users and applications emerge. That’s the difference between a compliance checkbox and true resilience.”
Email Security in an Age of AI-Generated Threats
Email remains the number one attack vector, but the nature of the threat has been transformed by generative AI. Attackers now craft business email compromise (BEC) messages that are grammatically flawless, contextually relevant and often indistinguishable from genuine communication. They can scrape a company’s website, LinkedIn profiles and recent news to personalise pretexts. Traditional secure email gateways (SEGs) that rely on reputation scoring and static signatures are swamped.
Specialist MSSPs like SEP2 layer advanced, AI-driven email security—such as Check Point’s Harmony Email & Collaboration—on top of native Microsoft 365 and Google Workspace defences. But they go further by embedding human-led threat hunting into the email flow. When a novel phishing campaign targets a local government’s finance department, SEP2’s analysts quickly reverse-engineer the indicators of compromise, create custom detection rules and silently remove the threat from all mailboxes across the organisation. This blend of AI triage and human expertise is what regulated bodies now insist upon.
“The public sector is a prime target because of the sensitive data it holds and the potential for disruption,” Starr explained. “We recently stopped a sophisticated, AI-generated BEC attack against a county council that would have redirected a £2.3 million social care payment. The email had perfect formatting, genuine-sounding internal references and even a spoofed approval chain. Our AI flagged the tone anomaly; our analyst validated it and blocked it in under 90 seconds.”
AI Security: Defending Against the Double-Edged Sword
AI is both a threat and a defence. Organisations are deploying AI copilots, machine learning models and natural language processing tools across their operations. These systems, however, introduce new attack surfaces: model poisoning, prompt injection, data leakage and adversarial manipulation. A specialist MSSP must not only secure the AI pipeline but also use AI to scale its own operations.
Check Point’s research arm has documented a 600% rise in attacks targeting AI infrastructure in the last 18 months. MSSPs that lack dedicated AI security expertise are ill-equipped to protect organisations relying on large language models for everything from clinical decision support to citizen service chatbots. SEP2 has trained a dedicated AI security practice that assesses model governance, monitors for anomalous inference queries and ensures that sensitive training data is not inadvertently exposed.
“You can’t outsource AI security to a generalist any more than you’d ask a GP to perform brain surgery,” Mitchelson said. “The threat surface is fundamentally different, and the response requires a deep understanding of data science, model behaviour and adversarial machine learning.”
The Public Sector and Healthcare Imperative
The public sector and healthcare verticals are at the sharp end of the threat landscape. Ransomware attacks on hospitals have led to cancelled surgeries, diverted ambulances and compromised patient outcomes. Local authorities have seen housing benefit systems frozen, and police forces have lost access to critical evidence platforms. These impacts are not just financial; they are human.
Regulators are responding. The UK’s National Cyber Security Centre (NCSC) now mandates Cyber Assessment Framework (CAF) alignment for critical national infrastructure, while the Care Quality Commission (CQC) and the Information Commissioner’s Office (ICO) have made it clear that board-level accountability for cyber resilience is non-negotiable. Specialist MSSPs provide the evidence trail, real-time risk scoring and incident response readiness that boards and regulators demand.
“We’re effectively an extension of the CISO’s office,” Starr noted. “We sit in on weekly risk committees, provide monthly governance reports that map directly to CAF outcomes and help trust boards understand their residual risk in plain English. That strategic layer is what separates us from a traditional SOC.”
The Check Point–SEP2 Partnership: A Blueprint for Specialist Delivery
The partnership between Check Point Software and SEP2 illustrates how vendor and MSSP can align to meet specialist demand. Check Point provides the unified security platform—spanning network, cloud, endpoint, mobile, IoT and email—while SEP2 layers on its operational wrapper: onboarding, policy architecture, 24/7 threat hunting, compliance reporting and executive briefings. The joint go-to-market focuses exclusively on sectors where deep, domain-specific knowledge is the differentiator.
This model is gaining traction beyond the UK. Check Point’s global MSSP partner programme has seen a 40% increase in specialist-focused providers over the past year, with particular growth in healthcare, financial services and energy. The company is investing in vertical-specific playbooks, regulatory mapping and AI co-pilot tools that enable MSSPs to deliver surgical precision at scale.
Looking Ahead: The Specialist Imperative
The message from Check Point and SEP2 is unambiguous: the era of the generalist MSSP is waning. As threat actors weaponise AI, as hybrid complexity deepens and as regulators sharpen their teeth, managed security must evolve from a commoditised alert pipeline into a strategic operational function. The organisations that thrive will be those that select an MSSP not on price per endpoint, but on demonstrable expertise in their specific technology estate, their regulatory obligations and their unique risk appetite.
For healthcare trusts, local councils and other regulated entities, the path forward is clear: partner with a provider that can speak the language of both the SOC and the boardroom; that can configure a SASE policy with the same fluency as it explains residual risk to a chief executive; and that sees security not as a set-and-forget utility but as a living, breathing discipline. Specialist MSSPs, armed with platforms like Check Point Infinity and the operational depth of firms like SEP2, are stepping into that role—and the market is rewarding them with growth.
