Hosting margins are thin. Renewals are competitive. Clients increasingly assume uptime and backups are baseline. If you run a hosting business or manage client sites under a care plan, security scanning is one of the easiest add-ons to productise — high perceived value, low delivery cost, and a natural fit alongside existing maintenance work.
Here's how to actually build it into your offering, price it, and deliver it without burning hours every month.
Why security scanning works as a hosting add-on
Most clients don't know their site is missing a Content Security Policy, leaking server versions in headers, or running on an SSL config that scores a C on modern scanners. They also don't know what any of that means — but they understand a letter grade and a PDF that says "your site improved from D to A".
That's the entire pitch. You're not selling them "HSTS preload". You're selling them:
- Peace of mind with a measurable score
- A monthly or quarterly report they can forward to their own stakeholders
- Protection against the specific issues insurers and compliance auditors now ask about
- A reason to renew at a higher tier next year
Decide what "security scanning" actually means in your offer
Don't be vague. Vague offers are hard to sell and harder to deliver. Pick a clear scope.
Tier 1: Configuration scanning
This covers everything externally visible: SSL/TLS configuration, HTTP security headers, Content Security Policy, cookie flags, DNS records (SPF, DMARC, DNSSEC, CAA), CORS policy, and information disclosure. This is what tools like WebSentry assess automatically and grade A–F.
Tier 2: Configuration + vulnerability scanning
Add automated checks for known CVEs in the CMS, plugins, and themes. For WordPress shops, this might mean integrating WPScan output. For Laravel or custom stacks, it means tracking dependency advisories.
Tier 3: Full managed security
Tier 2 plus malware scanning, file integrity monitoring, WAF management, and incident response time SLAs. This is a different product entirely and typically priced 5–10x higher.
Most agencies should start with Tier 1, because the delivery cost is near zero once you've set up the workflow.
Build the delivery workflow before you sell anything
The mistake most agencies make is selling a recurring service before they've automated it. Then every month becomes a scramble.
- Pick your scanner. You need something that produces consistent, client-readable output. WebSentry gives you an A–F grade and itemised findings across SSL, headers, CSP, cookies, DNS, and CORS — which is exactly the structure a non-technical client can digest.
- Establish a baseline. Run an initial scan on every client site you onboard. Save the grade and the report. This becomes your "before" state.
- Set a remediation budget. Decide how much engineering time per site is included in the onboarding fee — typically 1–3 hours to fix the easy wins (security headers, cookie flags, missing DMARC).
- Schedule recurring scans. Monthly is the sweet spot. Quarterly feels too infrequent; weekly creates noise.
- Define the deliverable. A one-page PDF or email with: current grade, change since last scan, issues fixed, issues outstanding, recommended next action.
Pricing that actually makes sense
Don't undercharge. Security is a premium-feeling service even when delivery is automated. Some realistic numbers:
- One-off audit + remediation: $200–$600 per site, depending on stack complexity
- Monthly scanning add-on (Tier 1): $20–$50 per site per month
- Bundled into a care plan: add $15–$30 to existing maintenance tiers
- Tier 2 with vulnerability monitoring: $75–$150 per site per month
If you manage 40 client sites and add $25/month for scanning, that's $12,000/year of near-pure margin once the workflow is set up.
Position it to clients without being technical
Your sales conversation should never start with "do you have a CSP?" Instead:
For new clients
Include a free initial security scan as part of your proposal. Show them their current grade. If it's a D or F (most sites are), you've created the problem you're about to solve. Quote the remediation as part of onboarding and include monthly scanning in the care plan.
For existing clients
Send them their current grade with no sales pitch. Just: "We ran our new security scanner across all client sites. Here's where yours stands. Happy to walk you through it." Most will ask what it costs to improve it.
For clients who push back on price
Frame it against the cost of a single incident. A defaced site, a compromised checkout, or a leaked admin panel costs more in one weekend than five years of monthly scanning. You're not selling a luxury — you're selling insurance with a measurable score attached.
What to fix first on almost every client site
When you run your first batch of scans, you'll see the same issues repeatedly. Knock these out and you'll move most sites from D/C to A/B in a couple of hours:
- Add
Strict-Transport-Securitywith a sensible max-age - Add
Content-Security-Policy(start in report-only mode if the site is complex) - Add
X-Content-Type-Options: nosniffandReferrer-Policy - Set
Secure,HttpOnly, andSameSiteon cookies - Publish a DMARC record, even if it's just
p=nonewith reporting - Remove server version disclosure from response headers
- Disable TLS 1.0/1.1 and weak ciphers at the load balancer or host level
White-label the reporting
Clients shouldn't see your scanner's branding — they should see yours. Either:
- Export the scan, drop it into a templated PDF with your logo, and send via your normal client comms
- Use a scanner that supports white-label reports or API access so you can build your own dashboard
WebSentry's report format is structured enough that you can pull the grade and findings into your own monthly client email without re-writing every line.
Track the metric that sells renewals
The single most powerful thing in your renewal conversation is a chart showing the client's security grade improving over twelve months. "Your site went from F to A under our care" is the kind of concrete outcome that justifies a price increase next year.
