Speeki Guardian™ experts are what sets us apart from any other assurance provider.


Speeki believes that assurance must be led by globally recognised experts in ESG and sustainability
At Speeki, we believe it’s essential that every expert involved in your assurance project is highly competent – not just broadly in ESG and sustainability, but across a wide range of specific areas. That competence must also be independently tested and certified on a regular basis.
To deliver high-quality assurance, our experts need proven knowledge and experience in the areas below.
Standards and frameworks
• How the CSRD, ESRS, IFRS S1 and S2, TCFD, TNFD and other standards operate

Personal capabilities

Speeki believes that our experts must have all of these skills – not just a background in financial accounting or audit.
As shown above, the expectations for sustainability assurance auditors are broad. Every one of these skills is essential to deliver effective, high-quality assurance.
Accounting knowledge may be relevant in some areas, but it’s only a small part of what’s required to be a competent assurance provider.
At Speeki, this is the baseline. If you meet these core requirements – and can prove it – you may be considered for Speeki Guardian™ assurance projects.
Speeki Guardian™ experts must have – and maintain – their skills through ongoing study, competency testing, client feedback, reviews and regular assessments.
You must prove that these skills exist through certifications and testing. Simply ticking a box is not enough.
You must meet our requirements for continuing education across all the areas listed above and show how you will maintain your knowledge each year.
You must also be open to feedback, oversight, shadowing and continuous improvement and development of your skills.
Your assurance team is a reflection of your company
Your assurance team should lead, support and add value. They need to act as an extension of your business while maintaining the independence and impartiality required for assurance.
Your assurance provider should align with your values
At Speeki, we see assurance as more than a once-a-year service. It’s an ongoing, shared commitment to improving sustainability reporting and meeting – or exceeding – stakeholder expectations.
Gain value from assurance, not just an opinion
We focus on results, not just reports. Speeki is committed to delivering value through strong support, deep business understanding and ESG expertise throughout every assurance project.
