The real tradeoff between cloud and on-premise audit software for an Indian CA firm is not security versus convenience — it is who takes on the operational responsibility for backups, security patching, and uptime: a cloud vendor whose entire business depends on doing that reliably across many firms, or the firm's own limited IT capacity doing it for itself, often without a dedicated IT function at all.
Why 'on-premise is more secure' usually doesn't hold up
On-premise software keeps data on a server the firm physically controls, which sounds like more security by default. In practice, most mid-sized CA firms don't have a dedicated IT security function patching servers promptly, monitoring for intrusion, or maintaining tested backups — which means the server is often less secured than a cloud vendor's infrastructure, not more, despite being physically closer.
Where on-premise genuinely wins
- Firms with a genuine, resourced IT function that can actually maintain the server to a high standard, rather than running on-premise by default and hoping.
- Specific regulatory or client contractual requirements that data never leave the firm's own physical infrastructure, which does occur for some sensitive clients.
- Environments with unreliable internet connectivity where cloud access during fieldwork would be a genuine, recurring operational problem.
Where cloud genuinely wins
- Firms without dedicated IT staff, where the realistic alternative to the vendor patching and backing up the system is nobody doing it reliably.
- Multi-branch firms needing the same up-to-date data accessible from different locations without maintaining separate infrastructure at each.
- Any firm wanting automatic version and security updates rather than a server that quietly falls behind on patches over time.
The outage question, specifically
A genuine operational concern with cloud software is what happens during a fieldwork day with poor or no internet access — this is worth asking any cloud vendor directly: does the tool support any offline capture that syncs later, or does fieldwork simply stop. An on-premise system accessed over a local network doesn't have this specific failure mode, though it has others.
| Dimension | Cloud | On-premise |
|---|---|---|
| Who patches and secures it | Vendor, as their core business | The firm, if it has the capacity to |
| Backup reliability | Usually automatic and tested by the vendor | Depends entirely on firm discipline |
| Access during connectivity loss | Needs an offline mode to not stop fieldwork | Works on local network regardless of internet |
| Data residency control | Depends on vendor's stated hosting location, not physical control | Physically controlled, but security depends on firm's own practices |
| Multi-branch access | Straightforward by design | Requires separate infrastructure or a VPN |
How we think about this
Lekhya is built cloud-first with India-based data residency stated plainly, on the view that most firms are better served by a vendor whose core business is reliably securing and backing up the system than by taking that on with limited internal IT capacity — but the right answer genuinely depends on what capacity a given firm actually has.
