Walk into most security programs and you'll find 60 to 80 tools — half overlapping, many half-deployed. The instinct is to blame procurement. The real cause is usually an architecture that was never written down, so every new threat got a new product instead of a decision.
Architecture that lasts starts with the question vendors hate: what problem are we actually solving, and do we already own something that solves it? Consolidation isn't about buying less — it's about knowing what each control is for and where the seams are.
Design for the org you'll be in two years, not the one you're in today. Identity, network, and data controls outlive any single product. Anchor the architecture to those layers — zero trust (NIST SP 800-207), SASE/SSE, a real identity fabric — and tools become replaceable parts, not load-bearing walls.
And document the why, not just the what. The architecture that survives a reorg or a CISO change is the one whose decisions are legible to the next person. That's a writing and communication discipline as much as a technical one.
