Observability Modernization
Infrastructure has changed. Observability hasn't.
Legacy platforms were built for static, pre-cloud infrastructure: vendor-specific storage, correlation after the fact, alert fatigue designed in rather than engineered out. That's not a feature gap you patch with a roadmap item. It's an architectural limitation, and it's why the tool you're renewing this year still can't tell you what it couldn't tell you five years ago.
Why the gap persists
Decades of investment. Still overwhelmed, still blind, still drowning in alerts.
Infrastructure teams haven't under-invested. They've invested in tools that were never built to work together. Normalization wasn't architecturally possible when most legacy platforms were designed, so they store vendor-specific data as-is and attempt correlation after the fact. Synthetic testing and telemetry monitoring were sold as separate modules, never truly integrated. Closing that gap isn't a roadmap item for an incumbent. It requires a ground-up rebuild.
What legacy platforms do
Correlated after the fact, if at all.
- Vendor-specific data stored as-is, correlated later
- Synthetics and telemetry sold as separate, bolted-together modules
- Static thresholds that alert on everything and mean nothing
- Conditional coverage: on-prem-only or SaaS-only, rarely both
What modern infrastructure requires
Normalized at ingestion, tuned continuously.
- Every source mapped to one schema the moment it arrives
- Active synthetic testing and telemetry monitoring, natively unified
- Alerts that learn your environment and get quieter over time
- Deployment flexibility, including fully air-gapped, from day one
The four pillars
Structural capabilities, not feature updates.
Each pillar is load-bearing on its own. Together, they're why closing this gap requires an incumbent to tear out its core architecture, not ship a point release.
Normalization at Ingest
Every data source, any vendor, any system, any location, is mapped into a unified schema the moment it enters the platform. Vendor-specific detail is preserved. Correlation, alerting, AI, and reporting are structurally more reliable from day one, because they're not reconstructing meaning after the fact.
Synthetics + Telemetry, Natively Unified
Active synthetic testing and continuous telemetry collection and monitoring in a single native system, not separate modules stitched together. Telemetry catches problems when they happen. Synthetic testing catches them before they do. A path failure at 2am gets identified before the 9am impact, not after.
- 01No context switching. One picture, not two consoles to reconcile.
- 02No correlation gap. Active and continuous signals share one data model.
Alert Auto-Tune™
ML-based learning that cuts alert noise by roughly 70%. It learns system behavior over time, recommends smarter thresholds, correlates and de-duplicates related alerts, and adds operational context: environment, business importance, network zone, tenant.
Deploy Anywhere
SaaS, on-premises, hybrid, or fully air-gapped, with day-zero deployment and no conditional coverage. Most platforms simply don't apply to air-gapped or on-prem-only environments. Parlon meets enterprises where they already are.
- 01No forced migration to SaaS. Deploy where your data has to live.
- 02Regulated and air-gapped ready. HIPAA-compliant, fully air-gapped deployments in production today.
Why now
The replacement cycle isn't coming. It's open.
Three forces are converging, and they compound.
AI workloads created new blind spots
AI and LLM workloads introduce failure modes legacy tools were never designed to see. Not a gap that gets patched, a gap that gets rebuilt around.
Buyers are actively evaluating replacements
73% of IT pros are likely to replace a network observability tool within two years. The top motivators: AI-driven insights and automation, better end-to-end visibility, and stronger support for modern architectures.

Incumbent economics are breaking down
Legacy renewal costs have surged 200–300%+ following private-equity-driven ownership changes at some vendors. Others have demanded hundreds of millions more at renewal, prompting customers to challenge the increases directly. Device-based pricing alone can exceed $1M a year before counting the 2–3 FTE needed just to administer the platform.
No rip-and-replace
Switching is not a project. It's a 30- to 60-day proof of value.
Parlon deploys alongside what you already have. It doesn't need to win on day one, it earns trust by making the incumbent look worse by comparison, on real traffic, in your environment.
Synthetic tests active: ICMP, HTTP, DNS, TCP, SSL. Installed alongside your existing stack. Zero disruption.

Savings beginWhat switching actually costs
3–8x lower total cost of ownership.
Three-year TCO, 500–5,000+ device deployments. Legacy platforms carry license, hardware, and professional-services costs Parlon's SaaS-first, normalization-first architecture was built to avoid.
| Cost category | Legacy platforms | Parlon |
|---|---|---|
| Annual license | $30K–$1M+ | $35K–$150K ACV |
| Infrastructure/hardware (Yr 1) | $10K–$300K | $0 (SaaS) |
| Professional services (Yr 1) | $5K–$500K | Minimal |
| Ops headcount (fully loaded/yr) | 1–5 FTE ($150K–$750K/yr) | 0.25–0.5 FTE (~$37K–$75K/yr) |
| Est. 3-year TCO | $400K–$4.5M+ | ~$175K–$600K |

Two things legacy platforms still do better
We won't pretend otherwise. Here's how we close the gap anyway.
Decades of vendor certifications and device support run deep. Parlon closes this through normalization: whatever you already have deployed feeds the same unified schema, so breadth becomes a data-source problem, not a platform limitation.
Legacy platforms have a longer on-prem operational history. Parlon's on-prem and fully air-gapped deployments are in production today, including HIPAA-compliant environments, and the gap closes fast because the architecture was built deploy-anywhere from day one.
Evidence
One platform replaced two, at about half the cost.
A healthcare enterprise operating 1,000+ clinic locations replaced its legacy network performance monitoring platform and a separate third-party synthetic testing tool with Parlon, in a single on-premise, air-gapped, HIPAA-compliant deployment.
“We found Parlon's capabilities beyond parity with the legacy vendors, and the simplicity of deployment and the cost were a significant value in themselves.”

Deployment, your terms
Wherever your data has to live.
Deployment flexibility isn't a checkbox here, it's the reason regulated and air-gapped environments can run Parlon at all.
SaaS
Fastest path to value. Fully managed, day-zero deployment.
On-premises
Runs entirely inside your infrastructure, no external dependency.
Hybrid
Mix SaaS and on-prem by environment, without splitting your data model.
Fully air-gapped
No external connectivity required. In production today, HIPAA-compliant.
Bring the renewal, the incident, or the tool you've stopped trusting. A founder will read it and tell you plainly whether a 30- to 60-day proof makes sense.
