Marketers have spent years defending against hackers, but the bigger risk may come from the software marketers use. Now that research has found martech vendors routinely taking companies\u2019 customer data<\/a>, marketers must put an end to it.<\/p>\n

That will require a sea change in how marketers think about vendors and solutions. It starts with understanding that every new integration is a security issue \u2014 not simply a software purchase. They need to apply the same discipline to approving software that they apply to approving campaigns: know what it\u2019s supposed to do, verify that it does only that, and review it regularly.<\/p>\n

Here are six steps to make that happen.<\/p>\n

Step 1: Understand what you\u2019re authorizing<\/h2>\n

Most marketers don\u2019t think of clicking \u201cauthorize\u201d as a security issue. But it is, and it\u2019s a big one. The failure to do that is where the problem begins.<\/p>\n

\u201cWhen we\u2019re talking about marketers and sales professionals, they \u2026 are not technical enough to know that there are red flags even happening that they should be aware of,\u201d said Clark Barron, founder of Blackout.<\/p>\n

Most marketers don\u2019t fully understand what they\u2019re approving when they connect a new application. The vendors pitch themselves as partners and, as long as the solution worked, marketers had no reason to question that.<\/p>\n

Depending on the permissions granted, a vendor may gain access to CRM records, sales pipelines, customer support tickets, internal emails, and other sensitive business information. It\u2019s also common to store employee and executive contacts in the same systems, so a single authorization can expose enterprise-scale amounts of information.<\/p>\n

And adding AI makes those problems bigger and faster.\u00a0<\/p>\n

Connecting an MCP server isn\u2019t just adding another tool \u2014 it\u2019s giving an external system access to work alongside your AI environment. Before approving that connection, marketers should understand what instructions the integration gives the AI model, what information it can access, and what actions it can take. The answers to those questions are rarely visible by default, so vendors must be required to disclose them as part of the approval process. If you don\u2019t know what\u2019s \u201cin the box,\u201d you can\u2019t know what the AI is being told to do.<\/p>\n

Step 2: Inventory every integration<\/h2>\n

Before reviewing permissions, organizations should know which applications are connected to their marketing stack, who approved them, why they were installed, and which systems they can access. Get rid of old integrations, abandoned applications, and duplicated tools before they become security liabilities.<\/p>\n

Step 3: Ensure vendors have only the access they need<\/h2>\n

Marketers must learn to ask vendors hard questions and adopt an adversarial mindset.\u00a0<\/p>\n

\u201cVerify first, and then trust,\u201d said Barron. \u201cWhen it comes to authorizing connections to your database, all of these vendors that are asking for access to your company\u2019s information ask them. Push them. And actually get it in writing.\u201d<\/p>\n

Doing that means marketers must learn everything they can about how digital processing agreements are drafted, how they work, and what a sub-processor actually is.\u00a0<\/p>\n

\u201cLearn about data brokerage practices and how that entire ecosystem works versus how it\u2019s presented,\u201d he said. \u201cBecause how it\u2019s presented is nonsense. It\u2019s just marketing fluff.\u201d<\/p>\n

Barron recommends starting every vendor review with six practical checks:<\/p>\n
