'what holds them together' is the definition.
I can't tell whether this definition defines the answer.

'entering firms abroad she envies' is the wordplay.
'entering' indicates putting letters inside.
'firms' becomes 'cos' (co is short for company - a business or firm).
'abroad' indicates anagramming the letters (abroad can mean moving around).
'she'+'envies'='sheenvies'
'sheenvies' is an anagram of 'hesivenes'.
'cos' placed around 'hesivenes' is 'COHESIVENESS'.

Can you help me to learn more?

(Another definition for cohesiveness that I've seen is " Tendency to stick together".)

I've seen this clue in The Daily Mail.
