The verdict in three sentences
The buyers of a cybersecurity firm in Amsterdam are CISOs, CIOs and compliance leads who type technical queries and forgive no approximation. Credible B2B SEO costs between 2,000 and 7,000 EUR a month, a 2026 ballpark seen in quotes from specialised Dutch agencies. Choose a provider able to write accurately about pentesting, SOC, NIS2 and DORA, and one that measures scoping requests, not visits.
Three ways to buy SEO, and what they cost in Amsterdam
Amsterdam is home to English-speaking B2B agencies, technology marketing specialists and senior freelancers. Most work in English by default; Dutch remains useful for SMEs, municipalities and the local public sector.
| Buying model | 2026 range (EUR, ballpark) | Upside | Limit |
|---|---|---|---|
| Senior freelancer, time and materials | 90 to 160 EUR per hour | Flexible, deep expertise | Limited capacity |
| Technical and content audit | 5,000 to 14,000 EUR | Full diagnosis | No execution included |
| Monthly retainer, English only | 2,000 to 4,500 EUR per month | Ongoing work | No Dutch |
| Monthly retainer, English and Dutch | 4,000 to 7,000 EUR per month | Covers public and private buyers | Heavier budget |
| Technical content by a security specialist | 500 to 1,200 EUR per article | Credibility with CISOs | Internal review needed |
| International B2B agency | 7,000 to 12,000 EUR per month | Multidisciplinary team | Little sector knowledge |
These ranges reflect typical quotes and public rate pages, with no statistical value. They exclude paid search and paid social on professional networks.
Red flags: when an agency does not understand your business
| Signal | What you hear | Why to refuse |
|---|---|---|
| Ranking promise | « Top 3 for pentest Amsterdam in 3 months » | No serious provider promises a ranking |
| Client logos without consent | « Let's show your clients to reassure buyers » | Confidentiality clauses, contractual risk |
| Invented incident stories | « Let's tell a typical attack story with a client » | No incident or client should ever be invented |
| Vague certifications | « Let's write certified on every page » | Only certifications actually held (CREST, ISO 27001) are cited |
| Bulk purchased links | « 30 links a month on tech blogs » | Penalty, damaged image with experts |
| Locked data | « The tools stay on our account » | You lose history when you leave |
| Report with no pipeline | Only traffic goes up | No link to signed contracts |
One point specific to your sector: your site sometimes handles urgent requests through an incident hotline. SEO must never degrade that page (loading, clarity of the number, form). On data, the GDPR (AVG in the Netherlands) and the Autoriteit Persoonsgegevens apply to forms and analytics tools; if you serve financial entities, your clients are themselves subject to DORA and sometimes to AFM supervision, which shapes how you present your services. This is not legal advice.
What to ask every agency
- Which queries are you targeting, with what volume? A good answer separates intent: « penetration testing company Netherlands », « NIS2 gap assessment », « managed SOC Amsterdam », « incident response retainer », « DORA TLPT provider ».
- Who writes about security? A writer with a real technical background, reviewed by one of your consultants.
- How will you work without naming our clients? Through methodology pages, anonymised sample deliverables and publications by your team.
- Which business metrics? Scoping requests, discovery calls, sources by page.
- What commitment length? Six months, then monthly, is reasonable.

The first 90 days you should demand
Need a professional website?
Kolonell builds websites that attract clients, optimized for the Sénégalese market. Free quote in 2 minutes.
Month 1: technical audit, service map (application pentesting, red teaming, managed SOC, incident response, NIS2 and ISO 27001 compliance), analysis of Dutch and European competitors. Month 2: one page per service with scope, methodology, deliverables, timelines and team profiles; a certifications page limited to what is actually held. Month 3: two expert pieces a month, for example a guide on NIS2 readiness for mid-sized companies, and a dashboard connected to the CRM. First qualified enquiries often arrive between 4 and 8 months.
Mini case study
Illustrative example: Grachtwall Security, 25 consultants in Amsterdam, compares two proposals. Agency A charges 2,200 EUR a month, English only, no CRM tracking. Agency B charges 5,000 EUR a month, English and Dutch, content reviewed by the technical team. Over 12 months, B costs 60,000 EUR against 26,400 EUR for A. If B generates 4 extra pentest engagements at 18,000 EUR each, additional revenue reaches 72,000 EUR, or 1.2 times the spend, before any recurring SOC contract.
FAQ
What SEO budget for a cybersecurity firm in Amsterdam?
Allow 2,000 to 4,500 EUR a month for English only and 4,000 to 7,000 EUR with Dutch, 2026 ballpark. A standalone audit costs 5,000 to 14,000 EUR.
Do we need a Dutch-language site?
If more than 20% of your prospects are Dutch SMEs or public bodies, yes. For an international client base, English can be enough to start.
Can we cite our certifications and clients?
Certifications yes, only those actually held and current. Clients only with their written consent, which remains rare in cybersecurity.
