Short answer: The best vulnerability scanner for an MSP or MSSP is the one that handles many clients cleanly — separate scopes, per-client reports, no data bleed between tenants — while pricing in a way that survives a changing client roster. Per-target subscriptions punish MSPs for onboarding/offboarding churn; a per-credit model with non-expiring credits matches lumpy, multi-client work far better. Top options in 2026: VulnScanners, ConnectSecure, HostedScan, and Intruder, each strong on a different axis.
TL;DR
- MSP requirements are different from a single security team's: it's about multi-client management, not one perimeter.
- The four things that matter most: client separation, per-client branded reports, pricing that tolerates churn, and a static source IP for allowlisting across clients.
- Avoid per-target subscriptions if your client list changes often — you'll pay for offboarded assets and idle inventory.
- Non-expiring credits are the single most MSP-friendly pricing feature.
What MSPs actually need (and single-team tools miss)
| Requirement | Why it matters for MSPs | |-------------|-------------------------| | Multi-client separation | Client A's data must never appear in client B's view or report | | Per-client reporting | Each client wants their own clean, ideally branded, PDF | | Flexible pricing | Rosters churn; you can't pay per-asset for clients you scan quarterly | | Static source IP | Every client's firewall needs one IP to allowlist | | Scan scheduling | Recurring scans per client without manual babysitting | | One console | Switching tools per client doesn't scale past a handful |
A tool built for a single in-house team optimizes for one perimeter monitored continuously. An MSP optimizes for N clients, each with different scope, cadence, and reporting — a genuinely different shape.
Why pricing model decides it for MSPs
MSP demand is lumpy: you onboard three clients this month, run a burst of assessments, then go quiet. Map that onto pricing models:
| Model | Fit for MSPs | Why | |-------|--------------|-----| | Per-target subscription | Poor–moderate | You pay for every asset every month, including clients you scan quarterly and assets you've offboarded | | Flat subscription | Moderate | Fine if volume is steady and high; wasteful if it isn't | | Per-scan | Moderate | Simple, but costs climb with recurring per-client scans | | Per-credit, non-expiring | Best | Pre-buy flexibility, spend it across any client, never forfeit unused balance |

The platforms compared
Positioning as of 2026 — verify current features and pricing with each vendor.
| Platform | MSP strength | Pricing | Best when | |----------|--------------|---------|-----------| | VulnScanners | Hosted Nmap+Nuclei+ZAP, per-client scans, PDF per scan | Per-credit, non-expiring | Variable client roster; you want flexible spend across clients | | ConnectSecure | Purpose-built MSP VM, PSA/RMM integrations, multi-tenant | MSP/agent-based | You're standardizing your whole book on one agent platform | | HostedScan | Risk dashboards, multi-target management | Subscription/target tiers | Continuous monitoring with strong risk reporting | | Intruder | Continuous attack-surface monitoring | Per-target subscription | Clients with stable, always-monitored perimeters |
VulnScanners for MSPs
Run hosted Nmap, Nuclei, and OWASP ZAP per client from one console, with a PDF report per scan and a stable source IP to hand each client for allowlisting. Because pricing is credit-based with non-expiring credits, onboarding and offboarding clients doesn't strand you with idle-asset fees — you spend credits where the work actually is. See our MSP pentesting and MSSP pages for how teams use it.
ConnectSecure
The most "MSP-native" option: built around multi-tenant vulnerability management with deep PSA/RMM integrations. If you want vulnerability data flowing into your existing MSP tooling and are ready to deploy agents across clients, it's a strong fit.
HostedScan
Polished risk dashboards and reporting across many targets. Works well for MSPs that want continuous monitoring and a clear risk view per client; typically subscription/target-tiered.
Intruder
Great continuous monitoring for clients with fixed perimeters. The per-target subscription model is its strength for always-on assets and its weakness for high-churn rosters.
How to choose
- My client roster changes a lot → per-credit, non-expiring (VulnScanners).
- I want deep PSA/RMM integration and agents → ConnectSecure.
- My clients are stable and I monitor them continuously → Intruder or HostedScan.
- I want the raw Nmap/Nuclei/ZAP stack per client without maintaining it → VulnScanners.
Checklist before you commit
- Can I keep each client's data and reports fully separate?
- Is there a branded/per-client PDF report?
- Does pricing survive onboarding and offboarding churn? Do credits expire?
- Is there a static source IP to give every client's firewall?
- Can I schedule recurring scans per client?
- Does it integrate with my PSA/RMM if I need that?
