Honest question: what social security hole are we talking about here? What kind of fraud? The gross majority of the social charges of a large company depend on employee wages. Having worked for a few CAC40 companies, knowing the makeup of their workforce, and looking at their public financial data, the numbers seem square.
On the other hand, every day I see small businesses with significant undeclared revenue and obvious money laundering schemes going on. France makes it very easy to anonymously report all sorts of crimes, from domestic violence and child neglect to terrorism, but only a selected few can report to TRACFIN.
Personally I can't wait for France to adopt a fiscal data module like the Belgian HoReCa black-box [0], and given the overreaching arms of the French fisc I'm surprised it hasn't already.
About unpaid dues (fraude aux cotisations), the highest financial authority (Cour des Comptes) estimated between 6.8 and 25 billion euros fraud annually in 2014, depending on the evaluation method. [0] Then there's dues exemptions. A study estimated 57 billion euros were exempted in 2015, 57% of which was compensated by the State's budget. [1]
We could also mention tax evasion and other schemes, which affect the ability of the national budget to compensate frauds. Despite arguments about the exact number, most agree big corporations pay less taxes than the small on average [2]. It's interesting to note the evolution over time of subsidiaries of CAC40 companies in fiscal paradises. [3]
Overall, there's plenty of fraud and "legal" exemptions on all levels. Quite enough to close the social security deficit.

I think that's happening. The law is clear that accounting software has to be certified since a few years (which has been a major hurdle for FLOSS projects). Personally, i'm not so much interested in such measures as most of the fraud is committed by the very wealthy and such measures could affect smaller businesses and common people in some ways: need to invest in more expensive accounting equipment/software, more difficulty for undocumented people to find honest jobs (though they'll still be able to work for big industrial groups who are famous for exploiting them).
