To emphasize that you are guaranteeing it personally, use the indirect object pronoun 'te' (to you): 'Te aseguro' is much stronger than just 'Aseguro'.

Frequently Asked Questions
How is 'aseguro' different from 'estoy seguro'?
'Aseguro' is a verb meaning 'I guarantee' or 'I make sure.' 'Estoy seguro' is a phrase using the verb 'estar' and the adjective 'seguro,' meaning 'I am sure' or 'I feel certain.'
Can I use 'aseguro' to mean 'I save' (like saving a file)?
No. While 'aseguro' means 'I make secure,' Spanish uses the verb 'guardar' or 'salvar' for saving data or files. 'Aseguro' is strictly for guarantees or physical fastening/insurance.
