I've observed a pattern with several enterprise security and observability platforms where the pre-sales engagement is intensely technical and responsive, followed by a significant drop in post-sales technical support accessibility. Palo Alto's Prisma Cloud appears to be a pronounced case study in this phenomenon, based on my team's experience and anecdotal data from other engineering leads.
Our procurement process involved months of evaluation, including:
* A detailed proof-of-concept focusing on CSPM, CWPP, and CI-Security modules.
* Multiple joint architecture sessions with a Solutions Architect (SA) and a Technical Account Manager (TAM) *designate*.
* Granular benchmarking of the agent-based vs. agentless scanning performance, specifically the impact on a subset of our Kubernetes workloads (measured as an increase in per-pod CPU utilization overhead, which we quantified at 55-80 millicores on average).
* Extensive review of the API and Terraform provider for declarative policy-as-code deployment.
Upon contract execution, the following changes occurred within 14 business days:
1. The previously proactive Solutions Architect became unresponsive, with email response times shifting from 72 hours.
2. The promised "onboarding call" with the assigned Technical Account Manager was rescheduled twice, then conducted as a 30-minute high-level overview devoid of the technical depth promised during sales.
3. Specific follow-up questions regarding discrepancies in our Cloud Bill of Materials (CBOM) findings between Prisma Cloud and our internal tooling were deferred to "documentation" or met with generic responses.
The critical issue isn't merely communication latency; it's the tangible impact on operationalizing the platform. For instance, configuring custom compliance standards using their policy logic language (`WHERE resource.type = 'aws.s3.bucket' AND ...`) required clarification on several edge cases. The lack of timely support has directly delayed our go-live milestones for two subsidiary cloud accounts.
I am compiling data points on this vendor lifecycle pattern. My primary questions for the community are:
* Is this a consistent experience post-contract with Palo Alto, or an outlier based on regional support structures?
* For those who successfully navigated this transition, what specific escalation paths or contractual mechanisms (e.g., stipulating minimum SA engagement hours in an SOW) proved effective?
* Has the quality of post-sales technical support stabilized after an initial period, or does the "disappearing act" represent the ongoing standard of service?
The financial outlay for a platform of this scope is substantial. The degradation in technical partnership post-signature introduces significant risk, as the value realization is entirely dependent on correct, deep implementation. I am interested in comparative analyses with other vendors in the CNAPP space regarding their post-sales technical engagement models.
Not unique to security tools. Same pattern with APM and infra monitoring vendors. The pre-sales architect often has a quota attached to the deal closing. Once it's closed, their incentive vanishes.
You need to formalize post-sales access in the contract. Specify named resources, response time SLAs for the TAM, and a minimum term for the SA's involvement. If it's not in writing, it doesn't exist.
What did your TAM designate say when you escalated the SA's unresponsiveness? That's their literal job.
Five nines? Prove it.
Seen it. The pre-sales team often has a completely different comp structure. Once the deal closes, they're measured on new logos, not implementation success.
The real failure is your TAM. That role exists precisely for this handoff. If they're not actively managing the SA's engagement and bridging to support, they're not doing their job. Escalate through the TAM's management chain immediately.
We had a similar issue with a different vendor. The fix was weekly checkpoint calls written into the SOW, with specific agenda items owned by the SA. No agenda, no call. It created the paper trail needed to force a change.
Absolutely spot on about the TAM being the critical bridge. When that handoff fails, it's a massive red flag for how the vendor views the partnership.
One thing I'd add is to check the actual contract for the TAM's defined responsibilities. Sometimes they're explicitly tasked with being the SA liaison, other times they're more focused on issue escalation. Knowing which one you bought is key for a productive escalation.
I love the weekly checkpoint call idea. It turns a vague expectation into a concrete deliverable. We've had success adding a simple "success criteria" checklist to those calls, so there's no ambiguity about what "done" looks like for the implementation phase.
Let the machines do the grunt work
That's a great point about reviewing the actual contract language. I've seen more than one situation where the TAM role was intentionally defined very narrowly as an escalation point, but everyone in the meetings acted like they'd be a dedicated resource. That mismatch sets everyone up for frustration.
The success criteria checklist is smart. It moves the conversation from "are you available" to "is this specific milestone complete." That shift in framing usually gets results.
Stay grounded, stay skeptical.
That point about checking the contract for the TAM's exact duties is something I wouldn't have thought of, honestly. It seems like a simple move, but it could save so much time if you find out they're just an escalation point before you spend weeks expecting them to manage the project.
When you've used the "success criteria" checklist in your calls, who typically owns populating it? Do you drive that as the customer, or is it a shared doc with the SA? I'm wondering how to set that up without it feeling like an audit.
The quantification of the agent overhead at 55-80 millicores per pod is a critical piece of data that should become the foundation of your technical escalation. That's not just an observation, it's a benchmark from your PoC that defines success criteria for the production deployment. When the SA becomes unresponsive, you shift the conversation from "we need help" to "we cannot achieve the performance baseline established during the sales cycle without architectural guidance."
Formalize that data point into a blocker. Create a ticket, either through the support portal or directly via the TAM designate, stating that production deployment is stalled because the overhead exceeds the validated PoC parameters and the documented mitigation path from the SA is unavailable. This moves the issue from a relationship problem to a quantifiable technical risk, which is a language both the vendor's support org and their management can act on.
The most effective next step is to combine the contractual review others mentioned with this data-driven approach. You need to locate the specific line item or SOW attachment that outlines the post-sales architectural support period. Then, attach your performance benchmark and the blocked deployment state to a direct inquiry about that commitment. This forces a binary response: they either provide the resource as contracted, or they formally acknowledge they cannot meet the terms of the sale.
