n8n Consultant for Secure, Production-Ready Workflows
Your n8n instance started as one builder's project. Now it syncs orders, routes leads and runs an AI agent, on settings nobody has reviewed since. As an n8n Select Partner, our n8n consultants review your instance, fix the workflows that fail, harden its security and hand everything back documented, or work beside your team while they build.

n8n Consulting From an Official Select Partner
Ovidius AI is a Select Partner in n8n's Expert Partner program and is listed in n8n's partner directory, where n8n points companies that want help building on its platform. For you, that means plan advice before you buy and instances set up the way n8n runs them in production.

01
Plan advice before you buy
Community, Business or Enterprise. We match features such as SSO, environments, Git version control, log streaming and external secrets to what your security team requires.
02
n8n's production patterns
Queue mode for volume, separate test and production environments, and workflows under version control, set up the way n8n documents them.
03
Advice that can turn into a build
When a review shows you need new workflows or agents, our n8n agency team builds them, and n8n Enterprise covers deployments at scale.
What Our n8n Consultants Do
Consulting starts from the instance you already run. These are the four kinds of work we take on.
Instance and workflow reviewWe read every workflow, credential and setting, then rank what we find by risk and by cost. Larger programs start with an AI Audit that maps the processes around n8n as well.
Remediation and rescueWorkflows a contractor left behind, agents that fail without telling anyone, a model provider you need to switch. We fix them in a test environment and run the fixed version beside the original until the outputs match.
Cost and performance tuningRepeated API calls, model calls on records that have not changed, and heavy workflows that belong in queue mode. Each shows up on a bill or as a slow run, and each has a fix.
An n8n expert beside your builderHours on call for the person who owns n8n on your team: pairing on changes, reviewing before production and answering what the docs do not. For whole teams, see n8n training.
n8n Security: What We Check on Every Instance
Self-hosting keeps your data in your own cloud, and it also makes the configuration your responsibility. Two n8n vulnerabilities published in January 2026 show where a default setup leaves you exposed.
CVE-2026-0863CVSS 8.5 · High
Python sandbox escape in the Code node
A signed-in user with basic permissions could break out of the Python sandbox and take over an instance running in Internal execution mode. In External mode, as in n8n's official Docker image, the code runs in a sidecar container instead of the main node.
What we check: execution mode and task runner setup
CVE-2025-68949CVSS 5.3 · Medium
Webhook IP allowlist bypass
From version 1.36.0 to before 2.2.0, the Webhook node matched allowlisted IP addresses as partial strings, so a request from an address outside the list could pass if it contained a listed one. n8n fixed it in 2.2.0.
What we check: n8n version and webhook authentication
Sources: CISA Vulnerability Summary for the Week of January 12, 2026 (SB26-020) and the US National Vulnerability Database entries for both CVEs.
The production checklist we run on your instance
VersionA release that carries the current security fixes
Execution modeCode nodes run in external task runners, not on the host
WebhooksHeader, basic or JWT authentication, never an IP allowlist alone
CredentialsScoped per environment, with an external secrets store on Enterprise
AccessSSO and role-based access, with no shared owner login
Execution dataPruned on a schedule, so personal data does not pile up in logs
FailuresAn error workflow and an alert on every production workflow
ChangesSeparate test and production, with workflows in Git
Four steps with one accountable team. How long each takes depends on the size of your instance, so we tell you before you commit.
ReviewAccess to your instance, then a written report We go through workflows, credentials, versions and settings, and rank every finding by risk and by cost.
FixHighest risk first We fix workflows in a test environment, then run the fixed and original versions side by side until the outputs match.
HardenSettings, access and alerts Upgrades, execution mode, webhook authentication, credential scoping, data pruning, and an error workflow that alerts your team.
Hand over or stay onDocumented, with access to everything Your team gets documentation for every change. If you want us to keep watch, AI managed services covers monitoring and upgrades. How we work covers each phase in full.
From a Stalled Odoo Project to an n8n Layer in Production
A Dutch Odoo implementation partner had spent a year trying to build appointment scheduling for a dental care group natively in Odoo. We moved the scheduling logic out of Odoo and into n8n.

Sync workflows between Odoo and Supabase
Ovidius did in weeks what we couldn't build natively in Odoo for a full year. They architected an AI-powered n8n layer on top of our ERP that now schedules well over a thousand appointments a week automatically. They are our preferred AI delivery partner.

Questions About Hiring an n8n Consultant
What does an n8n consultant do?
An n8n consultant reviews, fixes and hardens n8n instances and workflows, and advises the people who build in them. An n8n agency mostly builds new workflows. We do both. This page covers consulting, and our n8n agency page covers new builds.
Is self-hosted n8n secure?
It can be, once it is configured for production. The settings that matter most are the execution mode for Code nodes, webhook authentication, credential scoping, SSO and role-based access, execution data pruning and staying current with releases.
Our review checks each one against your instance and ranks what needs to change.
What does an n8n security review cover?
The n8n version and its security fixes, the execution mode for Code nodes, webhook authentication, credentials scoped per environment, SSO and role-based access, execution data pruning, an error workflow on every production workflow, and separate test and production environments in Git.
Each finding is ranked by risk and cost before anything is changed. Plan and licence questions are covered on our n8n Enterprise page.
Can you fix workflows someone else built?
Yes. We read the workflows as they are, fix them in a test environment, and run the fixed version beside the original until the outputs match, so nothing changes for your team until the fix is proven.
How do you charge for n8n consulting?
Fixes and rebuilds are scoped as a project with a written plan. Ongoing help is a retainer billed by the hour up to an agreed cap. We price both on the discovery call, once we have seen the size of your instance.
