Most small to medium-sized law firms don't know the answer to this question. Not because they haven't thought about it, but because it has never been tracked. Redaction gets absorbed into document review, lumped into case prep, and written off as just part of the job.

That's worth examining. Because "just part of the job" is still time, and time is still money.

The paralegal productivity problem

In 2025, the average utilization rate for law firms was just 38% — meaning legal professionals captured only about three billable hours out of an eight-hour workday. That number is already damaging. Now consider how much of the remaining five hours goes to tasks that are not just non-billable, but also non-essential when done by hand.

Manual redaction is one of those tasks.

A paralegal working through a standard PI production set — medical records, billing summaries, accident reports — has to read every page, carefully checking for Social Security numbers, medical record identifiers, and claimant information. They have to move slowly. The consequences of missing something are real. Then they do it again on the next case file.

If your firm handles 15 to 20 active cases, up to four hours per case adds up to 60–80 hours in manual redaction alone — before you count re-reviews when documents are updated or supplemented. That's less an operational detail than a part-time hire you didn't realize you were paying for.

What that time actually costs

With benefits and overhead, a paralegal hour at a small legal firm runs somewhere between $35 and $55. Multiply that across the firm's redaction hours each month, and the number adds up quickly.

But the dollar figure is only part of it.

The deeper cost is what doesn't get done. Every hour spent on manual document review is an hour not spent on intake, client communication, discovery prep, or the case management work that actually moves matters forward. In a high-volume environment, paralegal productivity is a firm's primary operational constraint. Burning it on a task that can be automated is a structural problem.

What happens when your practice grows?

Manual redaction doesn't scale — it gets less reliable as volume increases. As document volume grows, manual review leads to more fatigue, more inconsistency, and slower turnaround, leaving more room for mistakes. By Friday afternoon, your paralegal's capacity and accuracy are well below where they were Monday morning. A process that feels manageable at 10 cases starts showing cracks at 20.

That's not commentary on anyone's ability to do the job. That's just being human.

Manual vs. automated: what changes

The comparison comes down to three things:

Time
Consistency
Documentation

By moving to automated redaction, you save time, apply the same rules across every document no matter the time crunch, and improve compliance. No sensitive data is overlooked. No human errors slip through.

DataGuard handles this inside Microsoft 365, where your team already works. You define the policy once, and every document that goes out is automatically screened against it. Your paralegals don't change their workflow — they just stop spending their afternoons doing work a machine can do more consistently, in a fraction of the time, with a full audit log.

That's not just a productivity gain. It's what paralegal capacity looks like when it's pointed at the right work.
