I've been evaluating various XDR platforms for our CI/CD pipeline security monitoring, and Palo Alto's Cortex XDR trial was part of that process. The technical performance during the trial period was solid—latency benchmarks against our staging environment were acceptable, and the API integration for alert ingestion worked as documented.
However, since the trial concluded three weeks ago, I've received a persistent cadence of follow-up sales calls. It's become a significant distraction. My primary question is procedural: what is the most effective method to halt these communications?
I've already:
* Clearly stated we are in an evaluation phase with multiple vendors during the final call.
* Requested to be moved to a "no call" list via email with the sales representative.
* Attempted to use the email unsubscribe link in marketing materials (which appears separate from sales outreach).
The calls continue from different numbers. From an operational standpoint, this affects productivity. Has anyone else encountered this, and found a definitive point of contact or process that actually works? A direct email to a general compliance or data privacy address perhaps? I'm documenting vendor evaluation workflows, and post-trial vendor behavior is a non-trivial factor in our scoring matrix.
Numbers don't lie
Yeah, this is a classic and frustrating pattern. You've done the right things already by stating you're in evaluation and asking to be put on a no-call list.
When emailing the rep directly fails, I've had success going one level higher. Try finding the sales director or regional VP for your area on LinkedIn and sending a concise, polite message. Frame it as a process issue that's harming their brand perception with a potential customer. That usually gets the internal wheels turning faster than a generic compliance address.
Also, for the different numbers, next time they call, immediately ask for their full name and internal email and state you are recording the request to be placed on their corporate Do Not Contact list. That specific phrase can trigger compliance protocols.
Raise the signal, lower the noise.
The classic "no call list" request is unfortunately treated as a suggestion, not a command, by many sales orgs whose compensation is tied to activity metrics. Your email to the rep likely went into a black hole because it directly contradicts their quota-driven directives.
I've found the only reliably effective method is to invoke the formal legal channel. You mentioned documenting vendor behavior, which is good. Send a single email to both the sales rep's manager (find them on LinkedIn) and privacy@paloaalto.com, quoting the exact times and dates of the calls after your explicit opt-out. State clearly that the continued contact violates your request and constitutes harassment. This creates a compliance paper trail that their legal team cannot ignore.
Anything less formal is just you hoping their internal process will override their commission structure. It won't.
Trust but verify.
Both previous replies are correct about escalating above the rep, but they miss the underlying process flaw. The sales and marketing systems are likely not synchronized.
>Requested to be moved to a "no call" list via email with the sales representative.
That manual request probably never updated the lead status in their CRM (like Salesforce or HubSpot). The rep may have noted it, but automated call lists or lead recycling campaigns are driven by system flags, not notes. You need to force a system update.
The definitive method is to find the specific opt-out link in their privacy policy, which is legally binding for data processing. More effective than a generic email is to reply to any sales email with a clear, single-line demand: "Please update my lead status to 'Do Not Contact' in your CRM and confirm the system of record field has been changed." This demands a procedural action they must log. If it continues, forward that email chain to their Data Protection Officer, whose contact is in the privacy policy. This creates a GDPR/CCPA paper trail that their legal team must act on, as it's a data consent issue, not just a sales nuisance.
