The Case for a Dedicated Communications SOC Function

A senior executive recently recounted a sobering tale: a sophisticated social engineering attack that bypassed all their perimeter defenses, not through a network vulnerability, but through their customer support line. The attacker, armed with increasingly accessible deepfake voice technology, impersonated a high-value customer, initiated an account recovery, and within hours, siphoned off a substantial sum. This wasn't a one-off; similar narratives-ranging from data exfiltration to unauthorized financial transactions-are becoming alarmingly common, all leveraging the often-overlooked Achilles' heel of modern enterprises: communications infrastructure.

For years, the integrity of a company's communications systems-its contact centers, its IVRs, its messaging platforms-was largely an operational concern, relegated to IT help desks or customer service departments. Security, when considered at all, typically focused on network-level protection, firewalls, and data encryption. But the threat landscape has shifted dramatically. The bespoke, high-cost tools once exclusive to nation-state actors now reside in the hands of commodity cybercriminals. Moreover, the explosion of communication channels-from traditional telephony to encrypted messaging apps-creates an expansive, often fragmented, attack surface. The question isn't whether an organization needs a dedicated communications security function; it's how quickly they can build one without falling further behind.

Why A Dedicated Communications SOC Function Matters Now

Communications infrastructure, once a quarterly agenda item, has now firmly planted itself as a critical operational security imperative. The shift isn't subtle. Attackers, sensing a relatively soft target compared to hardened network perimeters, have redirected their efforts towards the pathways designed for human interaction. The reasons are familiar: attacker tooling is cheap, more channels are in production daily, and regulators-spurred by a rising tide of incidents-are finally paying attention. Boards, too, are inquiring, not just about "cyber risk," but specifically about the integrity of customer interactions and employee authentication channels. Organizations that delayed addressing this vector are already finding themselves a year or more behind, a gap that widens with every advance in generative AI, which makes credible impersonation almost trivial.

Consider the analogy of a medieval castle. For centuries, defenses focused on the walls and the gates. But what if the most vulnerable point wasn't the main gate, but the well, the drawbridge winch, or the messenger's postern door? That's the modern communications landscape. Attackers aren't always trying to breach the network directly; they're trying to manipulate the human interaction points that grant access through legitimate channels. And the long-tail search queries we're observing from within companies-"SOC policy template for contact center," for example, or "IVR fraud detection workflows"-suggest that executives are acutely aware of this shift and are quietly trying to build the frameworks to address it.

The Threat Pattern in Practice

There isn't a single control that will close this risk entirely. This is a layered defense problem, similar to protecting any other high-value asset. Each control makes an attack more expensive, and the objective is to elevate that cost to the point where the attacker's return-on-investment collapses, prompting them to seek a less prepared target. This is the foundational principle behind virtually every other category of security, and it applies with equal force here.

In the field, this pattern almost invariably manifests in workflows originally designed for convenience or exceptional circumstances. Think of recovery flows, manager override protocols, or after-hours intake systems-any mechanism built to maintain operational fluidity when standard processes hit a snag. Adversaries scrutinize these paths with the same rigor an auditor would, and they typically exploit them first. The defining characteristic of a successful attack isn't the sophistication of the attacker's toolkit, but rather how little friction they encounter once they've successfully infiltrated a legitimate workflow. If a system is designed to gracefully handle legitimate exceptions, it can equally gracefully handle malicious ones unless specific safeguards are embedded. Think of the IVR less as a phone tree and more as an unauthenticated API; the vulnerabilities quickly become clear.

What Effective Defense Looks Like

What fundamentally differentiates communications security from traditional cybersecurity controls is its direct interface with the customer experience. Imposing friction on a login flow is a familiar, if sometimes contentious, trade-off. However, introducing friction into a customer phone call or a chat interaction is a far less familiar proposition, often met with significant business pushback. To successfully navigate and resolve this resistance requires not just conviction, but data-driven insights. This necessitates measurement, and measurement, in turn, demands a structured program.

Our shorthand with clients is straightforward: "raise the cost." Effective controls do not promise to halt every single attempt. Instead, they aim to make a successful attack sufficiently cumbersome-in terms of time, specialized preparation, or financial outlay-that the attacker diverts their efforts towards an easier mark. This is precisely the logic underpinning every other mature security program, and it proves equally effective here when applied with discipline as a continuous program, rather than as a series of isolated projects.

Practical Next Steps for Your Team

If your organization is at the juncture of designing such a program, the initial step often involves a candid self-assessment. Write down the complete sequence of actions a single inbound interaction, say, a phone call or a chat message, can authorize within your most sensitive workflow. For each step, consider whether it could withstand a determined impersonation attempt. This isn't about identifying every possible flaw, but about pinpointing the most egregious vulnerabilities. Most teams emerge from this exercise with a concise, prioritized list of tactical changes that can be implemented and demonstrate tangible returns within a single quarter, often without requiring significant new tooling or investment. It's about optimizing what you already have, rather than rushing to buy more.

What We Are Watching Next

Over the next several quarters, the risks associated with communications infrastructure will increasingly migrate out of the security team's exclusive purview and into the domains of operations, legal, and customer experience. This is not only healthy but expected. It signifies an evolving understanding that communications security is a shared responsibility, deeply intertwined with business outcomes. Organizations that proactively plan for this integration, rather than react to it, will be far better positioned to maintain trust and operational integrity. We will continue to share insights and field observations as this critical pattern develops.
